[range-ops] Update known bitmasks using CCP for all operators.
Use bit-CCP to calculate bitmasks for all integer operators, instead
of the half-assed job we were doing with just a handful of operators.
This sets us up nicely for tracking known-one bitmasks in the next
release, as all we'll have to do is just store them in the irange.
All in all, this series of patches incur a 1.9% penalty to VRP, with
no measurable difference in overall compile time. The reason is
three-fold:
(a) There's double dispatch going on. First, the dispatch for the
range-ops virtuals, and now the switch in bit_value_binop.
(b) The maybe nonzero mask is stored as a tree and there is an endless
back and forth with wide-ints. This will be a non-issue next release,
when we convert irange to wide-ints.
(c) New functionality has a cost. We were handling 2 cases (plus
casts). Now we handle 20.
I can play around with moving the bit_value_binop cases into inlined
methods in the different range-op entries, and see if that improves
anything, but I doubt (a) buys us that much. Certainly something that
can be done in stage3 if it's measurable in any significant way.

the masks.

libstdc++: Avoid redundant checks in std::use_facet [PR103755]
We do not need to do bounds checks or a runtime dynamic_cast when using
std::has_facet and std::use_facet to access the default facets that are
guaranteed to be present in every std::locale object. We can just index
straight into the array and use a static_cast for the conversion.
This patch adds a new std::__try_use_facet function that is like
std::use_facet but returns a pointer, so can be used to implement both
std::has_facet and std::use_facet. We can then do the necessary
metaprogramming to skip the redundant checks in std::__try_use_facet.
To avoid having to export (or hide) instantiations of the new function
from libstdc++.so the instantiations are given hidden visibility. This
allows them to be used in the library, but user code will instantiate it
again using the definition in the header. That would happen anyway,
because there are no explicit instantiation declarations for any of
std::has_facet, std::use_facet, or the new std::__try_use_facet.

As Hongtao said, the fail on pentiumpro is caused by missing ISA check
since we are using emit_insn () through new builtins and it won't check
if the TARGET matches. Previously, the builtin in middle-end will check
that.
On pentiumpro, we won't have anything that supports any prefetch so that
it dropped into the pattern and then failed.
I have added the restrictions just like what middle-end builtin_prefetch
does. Also I added missing checks for PREFETCHI. Ok for trunk?

Do not specify NAN sign in frange::set_nonnegative.
After further reading of the IEEE 754 standard, it has become clear
that there are no guarantees with regards to the sign of a NAN when it
comes to any operation other than copy, copysign, abs, and negate.
Currently, set_nonnegative() is only used in one place in ranger
applicable to floating point values, when expanding unknown calls.
Since we already specially handle copy, copysign, abs, and negate, all

unswitching of outer loops

Change the name of array_at_struct_end_p to array_ref_flexible_size_p
The name of the utility routine "array_at_struct_end_p" is misleading
and should be changed to a new name that more accurately reflects its
real meaning.
The routine "array_at_struct_end_p" is used to check whether an array
reference is to an array whose actual size might be larger than its
upper bound implies, which includes 3 different cases:
A. a ref to a flexible array member at the end of a structure;
B. a ref to an array with a different type against the original decl;
C. a ref to an array that was passed as a parameter;
The old name only reflects the above case A, therefore very confusing
when reading the corresponding gcc source code.
In this patch, A new name "array_ref_flexible_size_p" is used to replace
the old name.

with this new name, and the corresponding comments were updated to make

Fix up foperator_abs::op1_range [PR107569]

+(0x0.fffffffffffff8p+1024)] +-NAN
which is correct except for the +-NAN part.
For r before the final step it makes sure to add -NAN if there is +NAN
in the lhs range, but the final r.union_ makes it unconditional +-NAN,
because the frange ctor sets +-NAN.
So, I think we need to clear it (or have some set variant which
says not to set NAN).
This patch fixes that, but isn't enough to fix the PR, something in
the assumptions handling is still broken (and the PR has other parts).

c++: Minimal handling of carries_dependency attribute
A comment in D2552R1:
"The only questionable (but still conforming) case we found was
[[carries_dependency(some_argument)]] on GCC, where the emitted diagnostic said that the
carries_dependency attribute is not supported, but did not specifically call out the syntax error
in the argument clause."
made me try the following patch, where we'll error at least
for arguments to the attribute and for some uses of the attribute
appertaining to something not mentioned in the standard warn
with different diagnostics (or should that be an error?; clang++
does that, but I think we never do for any attribute, standard or not).
The diagnostics on toplevel attribute declaration is still an
attribute ignored warning and on empty statement different wording.
The paper additionally mentions
struct X { [[nodiscard]]; }; // no diagnostic on GCC
and 2 cases of missing diagnostics on [[fallthrough]] (guess I should
file a PR about those; one problem is that do { ... } while (0); there
is replaced during genericization just by ... and another that
[[fallthrough]] there is followed by a label, but not user/case/default
label, but an artificial one created from while loop genericization.

analyzer: eliminate region_model::eval_condition_without_cm [PR101962]
In r12-3094-ge82e0f149b0aba I added the assumption that
POINTER_PLUS_EXPR of non-NULL is non-NULL (for PR analyzer/101962).
Whilst working on another bug, I noticed that this only works
when the LHS is known to be non-NULL via
region_model::eval_condition_without_cm, but not when it's known through
a constraint.
This distinction predates the original commit of the analyzer in GCC 10,
but I believe it became irrelevant in the GCC 11 rewrite of the region
model code (r11-2694-g808f4dfeb3a95f).
Hence this patch eliminates region_model::eval_condition_without_cm in
favor of all users simply calling region_model::eval_condition. Doing
so enables the "POINTER_PLUS_EXPR of non-NULL is non-NULL" assumption to
also be made when the LHS is known through a constraint (e.g. a
conditional).

libstdc++: basic_filebuf: don't flush more often than necessary [PR63746]
`basic_filebuf::xsputn` would bypass the buffer when passed a chunk of
size 1024 and above, seemingly as an optimisation.
This can have a significant performance impact if the overhead of a
`write` syscall is non-negligible, e.g. on a slow disk, on network
filesystems, or simply during IO contention because instead of flushing
every `BUFSIZ` (by default), we can flush every 1024 char.
The impact is even greater with custom larger buffers, e.g. for network
filesystems, because the code could issue `write` for example 1000X more
often than necessary with respect to the buffer size.
It also introduces a significant discontinuity in performance when
writing chunks of size 1024 and above.
Instead, it makes sense to only bypass the buffer if the amount of data
to be written is larger than the buffer capacity.

[PR24021] Implement PLUS_EXPR range-op entry for floats.
This is the range-op entry for floating point PLUS_EXPR. It's the
most intricate range entry we have so far, because we need to keep
track of rounding and target FP formats. This will be the last FP
entry I commit, mostly to avoid disturbing the tree any further, and
also because what we have so far is enough for a solid VRP.
So far we track NANs and signs correctly. We also handle relationals
(symbolics and numeric), both ordered and unordered, ABS_EXPR and
NEGATE_EXPR which are used to fold __builtin_isinf, and __builtin_sign
(__builtin_copysign is coming up). All in all, I think this provide
more than enough for basic VRP on floats, as well as provide a basis
to flesh out the rest if there's interest.
My goal with this entry is to provide a template for additional binary
operators, as they tend to follow a similar pattern: handle NANs, do
the arithmetic while keeping track of rounding, and adjust for NAN. I
may abstract the general parts as we do for irange's fold_range and
wi_fold.

CCP: handle division by a power of 2 as a right shift.
We have some code in range-ops that sets better maybe nonzero bits for
TRUNC_DIV_EXPR by a power of 2 than CCP does, by just shifting the
mask. I'd like to offload this functionality into the CCP mask
tracking code, which already does the right thing for right shifts.
The testcase for this change is gcc.dg/tree-ssa/vrp123.c and
gcc.dg/tree-ssa/pr107541.c.
gcc/ChangeLog:
* range-op.cc (operator_div::fold_range): Call
update_known_bitmask.
* tree-ssa-ccp.cc (bit_value_binop): Handle divisions by powers of
2 as a right shift.
