HSA: support alignment for hsa_symbols (PR hsa/70391)

	PR hsa/70391
	* hsa-brig.c (emit_directive_variable): Emit alignment
	according to hsa_symbol::m_align.
	* hsa-dump.c (hsa_byte_alignment): Move the function to
	another file.
	(dump_hsa_symbol): Dump alignment of HSA symbols.
	* hsa-gen.c (get_symbol_for_decl): Set-up alignment
	of a symbol.
	(gen_hsa_addr_with_align): New function.
	(hsa_bitmemref_alignment): Use newly added function.
	(gen_hsa_insns_for_load): Likewise.
	(gen_hsa_insns_for_store): Likewise.
	(gen_hsa_memory_copy): New argument added.
	(gen_hsa_insns_for_single_assignment): Respect
	alignment for assignments processed via
	gen_hsa_memory_copy.
	(gen_hsa_insns_for_direct_call): Likewise.
	(gen_hsa_insns_for_return): Likewise.
	(gen_function_def_parameters): Set default
	alignment.
	* hsa.c (hsa_object_alignment): New function.
	(hsa_byte_alignment): Pasted function.
	* hsa.h (hsa_symbol::m_align): New field.
