gcc/

	* config/aarch64/aarch64.c (POINTER_BYTES): New define.
	(aarch64_load_symref_appropriately): In the case of

	to generate new rtx; likewise to the case of SYMBOL_SMALL_GOT.
	(aarch64_expand_mov_immediate): In the case of SYMBOL_FORCE_TO_MEM,
	change to pass 'ptr_mode' to force_const_mem and zero-extend 'mem'
	if 'mode' doesn't equal to 'ptr_mode'.
	(aarch64_output_mi_thunk): Add an assertion on the alignment of
	'vcall_offset'; change to call aarch64_emit_move differently depending

	mode != ptr_mode.
	(aarch64_legitimize_reload_address): In the case of large

	based on it; change to use 'xmode' to generate the new rtx and
	reload.

	(aarch64_elf_asm_constructor): Change to use assemble_aligned_integer
	to output symbol.
	(aarch64_elf_asm_destructor): Likewise.
	* config/aarch64/aarch64.h (TRAMPOLINE_SIZE): Change to be dependent
	on TARGET_ILP32 instead of aarch64_trampoline_size.
	* config/aarch64/aarch64.md (movsi_aarch64): Add new alternatives
	of 'mov' between WSP and W registers as well as 'adr' and 'adrp'.

	(storewb_pair<GPI:mode>_<PTR:mode>): Likewise; rename to ...
	(storewb_pair<GPI:mode>_<P:mode>): ... this.
	(add_losym): Change to 'define_expand' and call gen_add_losym_<mode>
