Build fixes for OG12 on more recent GCC versions

This fixes a number of minor issues that can cause the build to fail on
recent versions of GCC.

2022-06-30  Kwok Cheung Yeung  <kcy@codesourcery.com>

	gcc/fortran/
	* openmp.cc (gfc_resolve_omp_allocate): Initialize tail to NULL.

(This should be a fixup to 491478d12b83e102f72858e8a871a25c951df293: 'Add
parsing support for allocate directive (OpenMP 5.0)')

2022-06-30  Kwok Cheung Yeung  <kcy@codesourcery.com>

	gcc/
	* omp-offload.cc (oacc_loop_get_cfg_loop): Cast tail_mark to
	gimple* for dump_printf.
	* tree-scalar-evolution.cc (oacc_ifn_call_extract): Remove
	unused variable 'call'.

(This should be a fixup to 491478d12b83e102f72858e8a871a25c951df293: 'Build
fix for 'openacc: Use Graphite for dependence analysis in "kernels" region')

2022-06-30  Kwok Cheung Yeung  <kcy@codesourcery.com>

	gcc/
	* omp-low.cc (usm_transform): Remove unused function argument.

(This should be a fixup to 54c2d861ac62e30ebf34a4e62ee0d55478a742b9: 'Build
fix for 'openmp: Use libgomp memory allocation functions with unified shared
memory')

2022-06-30  Kwok Cheung Yeung  <kcy@codesourcery.com>

	gcc/
	* omp-offload.cc (oacc_loop_warn_if_false_independent): Remove extra
	'.' at end of message.

(This should be a fixup to 01e6774b725ffa667efd818a46795189a281addf: 'Build
fix for 'openacc: Warn about "independent" "kernels" loops with
data-dependences')

2022-06-30  Tobias Burnus  <tobias@codesourcery.com>

	gcc/
	* graphite-isl-ast-to-gimple.cc (graphite_oacc_analyze_scop): Update
	arguments of dump_printf.

(This should be a fixup to a7e863fc4d54fb645fef05f01a024250184964bb:
'openacc: Add runtime alias checking for OpenACC kernels')
