gccrs: Fix higher ranked trait bounds computation of self
This updates the higher ranked trait bounds computation to handle ambigious
cases. When we have a slice for example:
let slice = &a[1..3];
This works by reusing the Index operator overload from libcore, so when the
index range of 1..3 is computed, the type system needs to compute what the
types of index are; this works by integer inference variables
Range<<integer>> that need to be unified with the impl Index for
Range<Usize> which computes the real type of usize for the index. This is
fine but what happens when we have the Copy and Clone traits bounds which
have implementations for all the primitive types i8, i16, i32, i64...
which is valid for any integer inference variable so the code prior to this
patch would have grabbed the first impl it would have found and used it
which is incorrect. When we have integer or float inference variables we
need to look for their respective defaults or emit an ambigious type bound
error.

gccrs: Support associated type bound arguments
This patch adds support for the GenercArgsBinding type, where you can
specify the associated types of a trait bound using `<Foo=i32>` style
syntax. Note that the type-resolution relys on the i32 impl for Add
as type resolution will resolve the `a+a` to the core::ops::Add method
so code generation will require this to exist.
I have ameded testsuite/rust/compile/bounds.rs as this code is wrongly
creating an HIR::GenericArgs with a trait-object type and causing issues.
the parsing is still correct but we dont have the mechanism to represent
this in AST and HIR properly. I think we will need a new HIR::GenericArgs
AssociatedTypeBindingBound or something similar. We are still lacking
bounds checking during are type coercions and unifications so running this
example using an f32 will wrongly pass type checking, this will need
addressed next.

- it remained in effect while running other dejagnu testsets
- it didn't quote correctly the argument list passed to it, which
caused test names to be surrounded by curly braces, as in:
UNSUPPORTED: {...}
This patch fixes both issues, obsoleting and reverting Jakub's change,
by dropping the overrider and renaming the saved proc back, and by

[RFA][Bug target/108892 ][13 regression] Force re-recognition after changing RTL structure of an insn
So as mentioned in the PR the underlying issue here is combine changes the form of an existing insn, but fails to force re-recognition. As a result other parts of the compiler blow up.
> /* Temporarily replace the set's source with the

> i2mod = temp;

> i2mod_new_rhs = copy_rtx (note);
> next = try_combine (insn, i2mod, NULL, NULL,

> {

> goto retry;
> } SET_SRC (set) = orig_src;
> SET_DEST (set) = orig_dest;
This code replaces the SET_SRC of an insn in the RTL stream with the contents of a REG_EQUAL note. So given an insn like this:
> (insn 122 117 127 2 (set (reg:DI 157 [ _46 ])
> (ior:DI (reg:DI 200)
> (reg:DI 251))) "j.c":14:5 -1
> (expr_list:REG_EQUAL (const_int
25769803782 [0x600000006])
> (nil)))
It replaces the (ior ...) with a (const_int ...). The resulting insn is passed to try_combine which will try to recognize it, then use it in a combination attempt. Recognition succeeds with the special define_insn_and_split pattern in the risc-v backend resulting in:
> (insn 122 117 127 2 (set (reg:DI 157 [ _46 ])
> (const_int
25769803782 [0x600000006])) "j.c":14:5 177 {*mvconst_internal}
> (expr_list:REG_EQUAL (const_int
25769803782 [0x600000006])
> (nil)))
This is as-expected. Now assume we were unable to combine anything, so try_combine returns NULL_RTX. The quoted code above restores SET_SRC (and SET_DEST) resulting in:
> (insn 122 117 127 2 (set (reg:DI 157 [ _46 ])
> (ior:DI (reg:DI 200)
> (reg:DI 251))) "j.c":14:5 177 {*mvconst_internal}
> (expr_list:REG_EQUAL (const_int
25769803782 [0x600000006])
> (nil)))
But this doesn't get re-recognized and we ICE later in LRA.
The fix is trivial, reset the INSN_CODE to force re-recognition in the case where try_combine fails.

ipa: Avoid another ICE when dealing with type-incompatibilities (PR 108959)
PR 108959 shows one more example where undefined code with type
incompatible accesses to stuff passed in parameters can cause an ICE
because we try to create a VIEW_CONVERT_EXPR of mismatching sizes:
1. IPA-CP tries to push one type from above,
2. IPA-SRA (correctly) decides the parameter is useless because it is
only used to construct an argument to another function which does not
use it and so the formal parameter should be removed,
3. but the code reconciling IPA-CP and IPA-SRA transformations still
wants to perform the IPA-CP and overrides the built-in DCE of
useless statements and tries to stuff constants into them
instead, constants of a type with mismatching type and size.
This patch avoids the situation in IPA-SRA by purging the IPA-CP
results from any "aggregate" constants that are passed in parameters
which are detected to be useless. It also removes IPA value range and
bits information associated with removed parameters stored in the same
structure so that the useless information is not streamed later on.

range-op-float: Fix reverse ops of comparisons [PR109386]

r13-6967 one) caused
FAIL: libphobos.phobos/std/math/algebraic.d execution test
FAIL: libphobos.phobos_shared/std/math/algebraic.d execution test
regressions, distilled into a C testcase below.
In the testcase, we have
!(u >= v)
condition where both u and v are results of fabs*, which guards
t1 = u u<= __FLT_MAX__;
and
t2 = v u<= __FLT_MAX__;
comparisons. From false u >= v where u and v have [0.0, +Inf] NAN
ranges we (incorrectly deduce that one of them is [nextafterf (0.0, 1.0), +Inf] NAN
and the other is [0.0, nextafterf (+Inf, 0.0)] NAN and from that deduce that
one of the comparisons is always true, because UNLE_EXPR with the maximum
representable number are false only if the value is +Inf and our ranges tell
that is not possible.
The bug is that the u >= v comparison determines a sensible range only when
it is true - we then know neither operand can be NAN and it behaves
correctly. But when the comparison is false, our current code gives
sensible answers only if the other op can't be NAN. If it can be NAN,
whenever it is NAN, the comparison is always false regardless of the other
value, so the other value needs to be VARYING.
Now, foperator_unordered_lt::op1_range etc. had code to deal with that
for op?.known_nan (), but as the testcase shows, it is enough if it may be a
NAN at runtime to make it VARYING.
So, the following patch replaces for all those BRS_FALSE cases of the normal
non-equality comparisons if (opOTHER.known_isnan ()) r.set_varying (type);
to do it also if maybe_isnan ().
For the unordered or ... comparisons, it is similar for BRS_TRUE. Those
comparisons are true whenever either operand is NAN, or if neither is NAN,
the corresponding normal comparison. So, if those comparisons are true
and other operand might be a NAN, we can't tell (VARYING), if it is false,
currently handling is correct.

rs6000: Fix vector_set_var_p9 by considering BE [PR108807]
As PR108807 exposes, the current handling in function
rs6000_expand_vector_set_var_p9 doesn't take care of big
endianness. Currently the function is to rotate the
target vector by moving element to-be-set to element 0,
set element 0 with the given val, then rotate back. To
get the permutation control vector for the rotation, it
makes use of lvsr and lvsl, but the element ordering is
different for BE and LE (like element 0 is the most
significant one on BE while the least significant one on
LE), this patch is to add consideration for BE and make
sure permutation control vectors for rotations are expected.
As tested, it helped to fix the below failures:

rs6000: Fix vector parity support [PR108699]
The failures on the original failed case builtin-bitops-1.c
and the associated test case pr108699.c here show that the
current support of parity vector mode is wrong on Power.
The hardware insns vprtyb[wdq] which operate on the least
significant bit of each byte per element, they doesn't match
what RTL opcode parity needs, but the current implementation
expands it with them wrongly.
This patch is to fix the handling with one more insn vpopcntb.

c++: friend template matching [PR107484]
Here friend matching tries to find a matching non-template friend and fails,
so we mark the friend as a template specialization to be determined later.
Then cplus_decl_attributes tries again to find a matching function and gets
confused by DECL_TEMPLATE_INSTANTIATION without DECL_TEMPLATE_INFO. But it
doesn't make sense for find_last_decl to be trying to match anything with
DECL_USE_TEMPLATE set; those are matched elsewhere.

ipa: Avoid constructing aggregate jump functions with huge offsets (PR 109303)
We are in the process of changing data structures holding information
about constants passed by reference and in aggregates to use unsigned

because that is what fell out of get_ref_base_and_extent at that time)
in order to conserve memory, especially at WPA time.

only create jump functions with offsets (plus sizes) that fit into the

build: Check that -lzstd can be linked
Recent Solaris 11.4 SRUs bundle zstd, but only the 64-bit libraries (no
idea why). Because of this, in 32-bit builds cc1 etc. fail to link with
undefined references to various ZSTD_* functions from lto-compress.o.
This happens because currently only the presence of <zstd.h> is
necessary to enable zstd support in lto-compress.cc etc.
This patch checks for libzstd first and disables zstd support if
missing.
Tested on sparc-sun-solaris2.11 with the system installation of zstd
(64-bit only) and a locally-compiled one (specified with --with-zstd).
