[nvptx] Verify dimension limits after applying defaults
There's a problem in oacc_validate_dims that when f.i. the worker dimension
is set using -fopenacc-dim=:32, and the vector_length is set using a
"vector_length (128)" clause, the compiler combines, accepts and emits the
values, while the combination of the two is invalid.
The reason for this is that while oacc_validate_dims validates the dimensions
using targetm.goacc.validate_dims before applying default or minimum values,
it does not do so afterwards.
Work around this in the nvptx port by applying the defaults from
oacc_default_dims at the end of nvptx_goacc_validate_dims_1, as
oacc_validate_dims would do it, and then apply the dimensions limits.

P0357R3 reference_wrapper for incomplete types
This patch implements the C++2a proposal to allow incomplete types in
std::reference_wrapper, which was previously undefined.
The change cannot be implemented for earlier standards, because prior to
C++2a std::reference_wrapper has a weak result type, so must inspect the
template argument to see if it defines a nested result_type member. That
is deprecated (but still required) in C++17, and removed from C++2a.
The removal of the base class from reference_wrapper is a potential ABI
change, as it could alter the layout of a type which derives from
reference_wrapper<T> and from an empty type with _Weak_result_type<T> as
a base class. Previously the repeated _Weak_result_type<T> base class
would have prevented the empty base-class optimization, but if
reference_wrapper<T> no longer derives from it, the empty class could be
placed at the same address as the reference_wrapper<T> base. In
practice, the only types which derive from _Weak_result_type or from
_Reference_wrapper_base_memfun or any of its base classes are non-empty
types defined in libstdc++: std::reference_wrapper, std::function, and
std::_Bind. As they are non-empty types, they are not eligible for EBO
anyway.

[nvptx] Don't allow vector_length 64 with num_workers 16
When using a compiler build with:
...
+#define PTX_DEFAULT_VECTOR_LENGTH PTX_CTA_SIZE
...
consider a test-case:
...
int
main (void)
{
#pragma acc parallel vector_length (64)
#pragma acc loop worker
for (unsigned int i = 0; i < 32; i++)
#pragma acc loop vector
for (unsigned int j = 0; j < 64; j++)
;
return 0;
}
...
If num_workers is 16, either because:
- we add a "num_workers (16)" clause on the parallel directive, or
- we set "GOMP_OPENACC_DIM=:16:", or
- the libgomp plugin chooses 16 num_workers
we run into an illegal instruction at runtime, because a bar.sync instruction
tries to use a barrier 16. The instruction is illegal, because ptx supports
only 16 barriers per CTA, and the valid range is 0..15.
The problem is that with a warp-multiple vector length, we use a code generation
scheme with a per-worker barrier. And because barrier zero is reserved for
per-cta barrier, only the remaining 15 barriers can be used as per-worker
barrier, and consequently we can't use num_workers larger than 15.
This problem occurs only for vector_length 64. For vector_length 32, we use a
different code generation scheme, and for vector_length >= 96, the maximum
num_workers is not big enough not to trigger this problem.
Also, this problem only occurs for num_workers 16. As explained above,
num_workers 15 is safe to use, and 16 is already the maximum num_workers for
vector_length 64.
This patch fixes the problem in both the compiler (handling "num_workers (16)")
and in the libgomp nvptx plugin (with and without "GOMP_OPENACC_DIM=:16:").

[libgomp, testsuite, openacc] Remove -foffload=-w in reduction-[1-5].c
Before the commit "[libgomp, testsuite, openacc] Don't use const int for
dimensions", the "const int" construct was used to set launch dimensions in
reductions-[1-5].c. In the case of -xc -O0, the const int is implemented as a
variable by the C front-end. Consequently, the nvptx back-end generated
warnings that vector_length was overridden to be hard-coded, rather than left to
be set at runtime. The test-cases silenced these warnings by switching off all
warnings in the accelerator compiler using "-foffload=-w".
Given that no warnings occur anymore, remove the "-foffload=-w" setting.

x86-64: {,V}CVT{,U}SI2Sx are ambiguous without suffix
For 64-bit these should not be emitted without suffix in AT&T mode (as
being ambiguous that way); the suffixes are benign for 32-bit. For
consistency also omit the suffix in Intel mode for {,V}CVTSI2SxQ.
The omission has originally (prior to rev 260691) lead to wrong code
being generated for the 64-bit unsigned-to-float/double conversions (as
gas guesses an L suffix instead of the required Q one when the operand
is in memory). In all remaining cases (being changed here) the omission
would "just" lead to warnings with future gas versions.
As a result, arrange to check for the L suffixes in 32-bit test cases.
In order for related test cases to actually test what they're supposed
to test, add (seemingly unrelated) a few empty "asm volatile()".
Presumably there are more where constant propagation voids the intended
effect of the tests, but these are ones helping make sure the assembler
actually still assembles correctly the output after the changes here.

[AArch64, 5/6] Enable BTI : Add new pass for BTI.
This patch is part of a series that enables ARMv8.5-A in GCC and
adds Branch Target Identification Mechanism.
This patch adds a new pass called "bti" which is triggered by the command
line argument -mbranch-protection whenever "bti" is turned on.
The pass iterates through the instructions and adds appropriated BTI
instructions based on the following:
* Add a new "BTI C" at the beginning of a function, unless its already
protected by a "PACIASP". We exempt the functions that are only called
directly.
* Add a new "BTI J" for every target of an indirect jump, jump table
targets, non-local goto targets or labels that might be referenced by
variables, constant pools, etc (NOTE_INSN_DELETED_LABEL).
Since we have already changed the use of indirect tail calls to only x16 and
x17, we do not have to use "BTI JC".

[AArch64, 3/6] Restrict indirect tail calls to x16 and x17
This patch is part of a series that enables ARMv8.5-A in GCC and
adds Branch Target Identification Mechanism.
This patch changes the registers that are allowed for indirect tail calls.
We are choosing to restrict these to only x16 or x17.
Indirect tail calls are special in a way that they convert a call statement
(BLR instruction) to a jump statement (BR instruction). For the best possible
use of Branch Target Identification Mechanism, we would like to place a
"BTI C" (call) at the beginning of the function which is only
compatible with BLRs and BR X16/X17. In order to make indirect tail calls
compatible with this scenario, we are restricting the TAILCALL_ADDR_REGS.
In order to use x16/x17 for this purpose, we also had to change the use
of these registers in the epilogue/prologue handling. For this purpose
we are now using x12 and x13 named as EP0_REGNUM and EP1_REGNUM as
scratch registers for epilogue and prologue.
