[PATCH 5/8] OpenMP, Fortran: Pass list number to gfc_free_omp_namelist

[Julian Brown <julian@codesourcery.com>]

This is a cleanup to avoid passing an ever-longer list of boolean
arguments to gfc_free_omp_namelist, in support of the Fortran "declare
mapper" implementation further along this patch series.

This patch isn't intended to cause any behavioural changes.

2023-09-05  Julian Brown  <julian@codesourcery.com>

gcc/fortran/
	* gfortran.h (gfc_free_omp_namelist): Update prototype.
	* match.cc (gfc_free_omp_namelist): Remove FREE_NS,
	FREE_ALIGN_ALLOCATOR, FREE_MEM_TRAITS_SPACE parameters and replace
	with LIST.
	* openmp.cc (gfc_free_omp_clauses, gfc_match_omp_clause_reduction,
	gfc_match_omp_clause_uses_allocators, gfc_match_omp_clauses,
	gfc_match_omp_allocate, gfc_match_omp_flush, resolve_omp_clauses):
	Update calls to gfc_free_omp_namelist.
	* st.cc (gfc_free_statement): Update call to gfc_free_omp_namelist.
