This fixes a large number of smaller and larger issues with the append_args
clause to 'declare variant' and adds Fortran support for it; it also contains
a larger number of testcases.

In particular, for Fortran, it also handles passing allocatable, pointer,
optional arguments to an interop dummy argument with or without value
attribute.  And it changes the internal representation such that dumping the
tree does not lead to an ICE.

gcc/c/ChangeLog:

	* c-parser.cc (c_finish_omp_declare_variant): Modify how
	append_args is saved internally.

gcc/cp/ChangeLog:

	* parser.cc (cp_finish_omp_declare_variant): Modify how append_args

	* pt.cc (tsubst_attribute): Likewise.

	handling as no longer called for it.
	* decl.cc (omp_declare_variant_finalize_one): Update append_args
	changes; fixes for ADL input.

gcc/fortran/ChangeLog:

	* gfortran.h (gfc_omp_declare_variant): Add append_args_list.
	* openmp.cc (gfc_parser_omp_clause_init_modifiers): New;
	splitt of from ...
	(gfc_match_omp_init): ... here; call it.
	(gfc_match_omp_declare_variant): Update to handle append_args
	clause; some syntax handling fixes.
	* trans-openmp.cc (gfc_trans_omp_declare_variant): Handle
	append_args clause; add some diagnostic.

gcc/ChangeLog:

	* gimplify.cc (gimplify_call_expr): For OpenMP's append_args clause
	processed by 'omp dispatch', update for internal-representation
	changes; fix handling of hidden arguments, add some comments and
	handle Fortran's value dummy and optional/pointer/allocatable actual
	args.

libgomp/ChangeLog:

This patch adds support for the `dispatch` construct and the `adjust_args`
clause to the Fortran front-end.

a side effect of the Fortran work.

2024 -> 2025

	* libgomp.texi (OpenMP Context Selectors): Document that 'kind' also
	accepts 'cpu'/'any' on host and 'any'/'nohost' on 'nohost' devices.

Follow up to r15-5392-g884637b6362391. As the name implies,
GOMP_OFFLOAD_openacc_async_construct is also externally called.
Hence, partially revert previous commit to permit unlocking handling
in oacc-async.c's lookup_goacc_asyncqueue by not failing fatally.

Hence, also the other (indirect) callers had to be updated:
GOMP_OFFLOAD_dev2dev fails now with 'false' and
GOMP_OFFLOAD_async_run fatally.

libgomp/ChangeLog:

	* plugin/plugin-gcn.c (GOMP_OFFLOAD_dev2dev, GOMP_OFFLOAD_async_run):
	Handle omp_async_queue == NULL after call to maybe_init_omp_async.
	(GOMP_OFFLOAD_openacc_async_construct): Use error not fatal error,
	partially reverting r15-5392.

PTX '%dynamic_smem_size' was "Introduced in PTX ISA version 4.1", and
"Requires 'sm_20' or higher".  Given that GCC/nvptx generally supports
'sm_20', only the PTX ISA version matters here, and that's all fine if
just using GCC's defaults.  Follow-up to
commit e9a19ead
"openmp, nvptx: low-lat memory access traits".

	libgomp/
	* libgomp.texi: Clarify nvptx 'omp_low_lat_mem_space'
	documentation.

Fortran: Use OpenACC's acc_on_device builtin, fix OpenMP' __builtin_is_initial_device: Revert 'gimple_fold_builtin_acc_on_device' change

The motivation of the 'gimple_fold_builtin_acc_on_device' change in
commit 3269a722
"Fortran: Use OpenACC's acc_on_device builtin, fix OpenMP' __builtin_is_initial_device"
is unclear, and it unnecessarily diverges GCC's (default)
'--disable-offload-targets' vs. '--enable-offload-targets=[...]'
configurations.

	PR testsuite/82250
	gcc/
	* gimple-fold.cc (gimple_fold_builtin_acc_on_device): Revert last
	change.
	libgomp/
	* testsuite/libgomp.oacc-c-c++-common/routine-nohost-1.c: Revert
	last change.

Fixed a check to permit [[omp::decl(allocate,...)]] parsing in C.

Additionaly, we discussed that 'allocate align' should not affect
'alignof' to avoid issues like with:

  int a;
  _Alignas(_Alignof(a)) int b;
  #pragma omp allocate(a) align(128)
  _Alignas(_Alignof(a)) int c;

Thus, the alignment is no longer set in the C and Fortran front ends,
but for static variables now in varpool_node::finalize_decl.
(For stack variables, the alignment is handled in gimplify_bind_expr.)

NOTE: 'omp allocate' is not yet supported in C++.

gcc/c/ChangeLog:

	* c-parser.cc (c_parser_omp_allocate): Only check scope if
	not in_omp_decl_attribute. Remove setting the alignment.

gcc/ChangeLog:

	* cgraphunit.cc (varpool_node::finalize_decl): Set alignment
	based on OpenMP's 'omp allocate' attribute/directive.

gcc/fortran/ChangeLog:

	* trans-decl.cc (gfc_finish_var_decl): Remove setting the alignment.

libgomp/ChangeLog:

	* libgomp.texi (Memory allocation): Mention (non-)effect of 'align'
	on _Alignof.
	* testsuite/libgomp.c/allocate-7.c: New test.

gcc/testsuite/ChangeLog:

	* c-c++-common/gomp/allocate-18.c: Check that alignof is unaffected
	by 'omp allocate'.
	* c-c++-common/gomp/allocate-19.c: Likewise.
