[AArch64] Rename cmp_result iterator
The comparison results provided by the V_cmp_result/v_cmp_result
attribute were simply the corresponding integer vector. We'd also
like to have easy access to the integer vector for SVE, but using
"cmp_result" would be confusing because SVE comparisons return
predicates instead of vectors. This patch therefore renames the
attributes to the more general V_INT_EQUIV/v_int_equiv instead.
As to the capitalisation: there are already many iterators that use
all lowercase vs. all uppercase names to distinguish all lowercase
vs. all uppercase expansions (e.g. fcvt_target and FCVT_TARGET).
It's also the convention used for the built-in mode/MODE/code/CODE/etc.
attributes. IMO those names are easier to read at a glance, rather than
relying on a single letter's difference.

[AArch64] Remove use of wider vector modes
The AArch64 port defined x2, x3 and x4 vector modes that were only used
in the rtl for the AdvSIMD LD{2,3,4} patterns. It seems unlikely that
this rtl would have led to any valid simplifications, since the values
involved were unspecs that had a different number of operands from the
non-dreg versions. (The dreg UNSPEC_LD2 had a single operand, while
the qreg one had two operands.)
As it happened, the patterns led to invalid simplifications on big-
endian targets due to a mix-up in the operand order, see Tamar's fix
in r240271.
This patch therefore replaces the rtl patterns with dedicated unspecs.
This allows the x2, x3 and x4 modes to be removed, avoiding a clash
with 256-bit and 512-bit SVE.

Add a partial_subreg_p predicate
This patch adds a partial_subreg_p predicate to go alongside
paradoxical_subreg_p.
Like the paradoxical_subreg_p patch, this one replaces some tests that
were based on GET_MODE_SIZE rather than GET_MODE_PRECISION. In each
case the change should be a no-op or an improvement.
The regcprop.c patch prevents some replacements of the 82-bit RFmode
with the 80-bit XFmode on ia64. I don't understand the target details
here particularly well, but from the way the modes are described in
ia64-modes.def, it isn't valid to assume that an XFmode can carry an
RFmode payload. A comparison of the testsuite assembly output for one
target per CPU showed no other differences.
Some of the places changed here are tracking the widest access mode
found for a register. The series tries to standardise on:
if (partial_subreg_p (widest_seen, new_mode))
widest_seen = new_mode;
rather than:
if (paradoxical_subreg_p (new_mode, widest_seen))
widest_seen = new_mode;
Either would have been OK.

[66/77] Use scalar_mode for constant integers
This patch treats the mode associated with an integer constant as a
scalar_mode. We can't use the more natural-sounding scalar_int_mode
because we also use (const_int 0) for bounds-checking modes. (It might
be worth adding a bounds-specific code instead, but that's for another
day.)
This exposes a latent bug in simplify_immed_subreg, which for
vectors of CONST_WIDE_INTs would pass the vector mode rather than
the element mode to rtx_mode_t.
I think the:
/* We can get a 0 for an error mark. */
|| GET_MODE_CLASS (mode) == MODE_VECTOR_INT
|| GET_MODE_CLASS (mode) == MODE_VECTOR_FLOAT
in immed_double_const is dead. trunc_int_mode (via gen_int_mode)
would go on to ICE if the mode fitted in a HWI, and surely plenty
of other code would be confused to see a const_int be interpreted
as a vector. We should instead be using CONST0_RTX (mode) if we
need a safe constant for a particular mode.
We didn't try to make these functions take scalar_mode arguments
because in many cases that would be too invasive at this stage.
Maybe it would become feasible in future. Also, the long-term
direction should probably be to add modes to constant integers
rather than have then as VOIDmode odd-ones-out. That would remove
the need for rtx_mode_t and thus remove the question whether they
should use scalar_int_mode, scalar_mode or machine_mode.
The patch also uses scalar_mode for the CONST_DOUBLE handling
in loc_descriptor. In that case the mode can legitimately be
either floating-point or integral.

The main scalar integer block in simplify_const_unary_operation
had the condition:
if (CONST_SCALAR_INT_P (op) && width > 0)

This patch replaces it with a check for a scalar_int_mode instead.
It also uses the number of bits in the input rather than the output
mode to determine the result of a "count ... bits in zero" operation.
(At the momemnt these modes have to be the same, but it still seems
conceptually wrong to use the number of bits in the output mode.)

[47/77] Make subroutines of nonzero_bits operate on scalar_int_mode
nonzero_bits1 assumed that all bits of a floating-point or vector mode

modes that are likely to be useful are scalar integer ones.
This patch moves the mode class check to nonzero_bits itself, along

[43/77] Use scalar_int_mode in simplify_comparison
The main loop of simplify_comparison starts with:
if (GET_MODE_CLASS (mode) != MODE_INT
&& ! (mode == VOIDmode
&& (GET_CODE (op0) == COMPARE || COMPARISON_P (op0))))
break;
So VOIDmode is only acceptable when comparing a COMPARE,
EQ, NE, etc. operand against a constant. After this, the loop
calls simplify_compare_const to:
(a) bring the constant op1 closer to 0 where possible and
(b) use nonzero_bits and num_sign_bit_copies to get a simpler
constant.
(a) works for both integer and VOID modes, (b) is specific
to integer modes.
The loop then has a big switch statement that handles further
simplifications. This switch statement checks for COMPARISON_P
codes but not for COMPARE.
This patch uses scalar_int_mode to make the split between
(a) and (b) more explicit. It also takes the COMPARISON_P
handling out of the switch statement and does it first,
so that the rest of the loop can treat the mode as a
scalar_int_mode.
