[61/77] Use scalar_int_mode in the AArch64 port
This patch makes the AArch64 port use scalar_int_mode in various places.
Other ports won't need this kind of change; we only need it for AArch64
because of the variable-sized SVE modes.
The only change in functionality is in the rtx_costs handling
of CONST_INT. If the caller doesn't supply a mode, we now pass
word_mode rather than VOIDmode to aarch64_internal_mov_immediate.

the right choice in calls related to secondary memory reloads (the ones

Make more use of int_mode_for_size
This patch converts more places that could use int_mode_for_size instead
of mode_for_size. This is in preparation for an upcoming patch that
makes mode_for_size itself return an opt_mode.
require () seems like the right choice in expand_builtin_powi
because we have got past the point of backing out. We go on to do:
op1 = expand_expr (arg1, NULL_RTX, mode2, EXPAND_NORMAL);
if (GET_MODE (op1) != mode2)
op1 = convert_to_mode (mode2, op1, 0);
which would be invalid for (and have failed for) BLKmode.
In get_builtin_sync_mode and expand_ifn_atomic_compare_exchange,
the possible bitsizes are {8, 16, 32, 64, 128}, all of which give
target-independent integer modes (up to TImode). The comment above
the call in get_builtin_sync_mode makes clear that an integer mode
must be found.
We can use require () in expand_builtin_atomic_clear and
expand_builtin_atomic_test_and_set because there's always an integer
mode for the boolean type. The same goes for the POINTER_SIZE request
in layout_type. Similarly we can use require () in combine_instructions
and gen_lowpart_common because there's always an integer mode for
HOST_BITS_PER_WIDE_INT (DImode when BITS_PER_UNIT == 8), and
HOST_BITS_PER_DOUBLE_INT (TImode).
The calls in aarch64_function_value, arm_function_value,
aapcs_allocate_return_reg and mips_function_value_1 are handling
cases in which a big-endian target passes or returns values at
the most significant end of a register. In each case the ABI
constrains the size to a small amount and does not handle
non-power-of-2 sizes wider than a word.
The calls in c6x_expand_movmem, i386.c:emit_memset,
lm32_block_move_inline, microblaze_block_move_straight and
mips_block_move_straight are dealing with expansions of
block memory operations using register-wise operations,
and those registers must have non-BLK mode.
The reason for using require () in ix86_expand_sse_cmp,
mips_expand_ins_as_unaligned_store, spu.c:adjust_operand and
spu_emit_branch_and_set is that we go on to emit non-call
instructions that use registers of that mode, which wouldn't
be valid for BLKmode.

ix86_finalize_stack_frame_flags has been extended to eliminate frame
pointer when the new stack frame isn't needed with and without
-maccumulate-outgoing-args as well as -fomit-frame-pointer. Since stack
access with larger alignment may be optimized out, to decide if stack
realignment is needed, we need to not only check for stack frame access,
but also verify the alignment of stack frame access. Since alignment of
memory access via arg_pointer is set up by caller, not by callee, we
should find the maximum stack alignment from the stack frame access
instructions via stack pointer and frame pointrer to avoid stack
realignment when stack alignment needed is less than incoming stack

alignment code.
When the requested alignment is lower than the stack alignment, no
extra alignment is needed. If the requested alignment is higher,
we need to increase the size by the difference of the requested
alignment and the stack alignment. As a result, the alloca alignment
is exactly as expected:
alloca (16):
sub sp, sp, #16
mov x1, sp
alloca (x):
add x0, x0, 15
and x0, x0, -16
sub sp, sp, x0
mov x0, sp
__builtin_alloca_with_align (x, 512):
add x0, x0, 63
and x0, x0, -16
sub sp, sp, x0
add x0, sp, 63
and x0, x0, -64

Turn HARD_REGNO_CALL_PART_CLOBBERED into a target hook
The SVE patches change the size of a machine_mode from a compile-time
constant to a runtime invariant. However, target-specific code can
continue to treat the modes as constant-sized if the target only has
constant-sized modes.
The main snag with this approach is that target-independent code still
uses macros from the target .h file. This patch is one of several that
converts a target macro to a hook.
