* config/aarch64/aarch64.c (POINTER_BYTES): New define.
(aarch64_load_symref_appropriately): In the case of
SYMBOL_SMALL_ABSOLUTE, use the mode of 'dest' instead of Pmode
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
on whether 'Pmode' equals to 'ptr_mode' or not; use 'POINTER_BYTES'
to calculate the upper bound of 'vcall_offset'.
(aarch64_cannot_force_const_mem): Change to also return true if
mode != ptr_mode.
(aarch64_legitimize_reload_address): In the case of large
displacements, add new local variable 'xmode' and an assertion
based on it; change to use 'xmode' to generate the new rtx and
reload.
(aarch64_asm_trampoline_template): Change to generate the template
differently depending on TARGET_ILP32 or not; change to use
'POINTER_BYTES' in the argument passed to assemble_aligned_integer.
(aarch64_trampoline_size): Removed.
(aarch64_trampoline_init): Add new local constant 'tramp_code_sz'
and replace immediate literals with it. Change to use 'ptr_mode'
instead of 'DImode' and call convert_memory_address if the mode
of 'fnaddr' doesn't equal to 'ptr_mode'.
(aarch64_elf_asm_constructor): Change to use assemble_aligned_integer
to output symbol.
(aarch64_elf_asm_destructor): Likewise.

of 'mov' between WSP and W registers as well as 'adr' and 'adrp'.
