[AArch64] Remove SVE XFAILs
These tests started passing after r257293, which had the side-effect
of renumbering the SSA names and leaving the COND_EXPRs in their
natural order.
This does show a deeper underlying issue that code generation is too
sensitive to internal things like SSA_NAME versions, but it no longer
affects these particular tests (for now).

compiler: update iota handling, fix using iota in array length
CL 71750 changed the definition of how iota works. This patch updates
gccgo for the new definition.
We've been mishandling iota appearing in a type that appears in a
const expression, as in `c = len([iota]int{})`. Correct that by copying
type expressions when we copy an expression. For simplicity only copy
when it can change the size of a type, as that is the only case where
iota in a type can affect the value of a constant (I think). This is
still a bunch of changes, but almost all boilerplate.

[AArch64] Fix SVE testsuite failures for ILP32 (PR 83846)
The SVE tests are split into code-quality compile tests and runtime
tests. A lot of the former are geared towards LP64. It would be
possible (but tedious!) to mark up every line that is expected to work
only for LP64, but I think it would be a constant source of problems.
Since the code has not been tuned for ILP32 yet, I think the best
thing is to select only the runtime tests for that combination.
They all pass on aarch64-elf and aarch64_be-elf except vec-cond-[34].c,
which are unsupported due to the lack of fenv support.
The patch also replaces uses of built-in types with stdint.h types
where possible. (This excludes tests that change the endianness,
since we can't assume that system header files work in that case.)

[AArch64] Handle SVE subregs that are effectively REVs
Subreg reads should be equivalent to storing the inner register to
memory and loading the appropriate memory bytes back, with subreg
writes doing the reverse. For the reasons explained in the comments,
this isn't what happens for big-endian SVE if we simply reinterpret
one vector register as having a different element size, so the
conceptual store and load is needed in the general case.
However, that obviously produces poor code if we do it too often.
The patch therefore adds a pattern for handling the operation in
registers. This copes with the important case of a VIEW_CONVERT
created by tree-vect-slp.c:duplicate_and_interleave.
It might make sense to tighten the predicates in aarch64-sve.md so
that such subregs are not allowed as operands to most instructions,
but that's future work.
This fixes the sve/slp_*.c tests on aarch64_be.

[AArch64] Prefer LD1RQ for big-endian SVE
This patch deals with cases in which a CONST_VECTOR contains a
repeating bit pattern that is wider than one element but narrower
than 128 bits. The current code:
* treats the repeating pattern as a single element
* uses the associated LD1R to load and replicate it (such as LD1RD
for 64-bit patterns)
* uses a subreg to cast the result back to the original vector type
The problem is that for big-endian targets, the final cast is
effectively a form of element reverse. E.g. say we're using LD1RD to load
16-bit elements, with h being the high parts and l being the low parts:
+-----+-----+-----+-----+-----+----
lanes | 0 | 1 | 2 | 3 | 4 | ...
+-----+-----+-----+-----+-----+----
memory bytes |h0 l0 h1 l1 h2 l2 h3 l3 h0 l0 ....
+----------------------------------
V V V V V V V V
----------+-----------------------+
register .... | 0 |
after ----------+-----------------------+ lsb
LD1RD .... h3 l3 h0 l0 h1 l1 h2 l2 h3 l3|

register ----+-----+-----+-----+-----+-----+ lsb
contents .... h0 l0 h3 l3 h2 l2 h1 l1 h0 l0|
----------------------------------+
A later patch fixes the handling of general subregs to account
for this, but it means that we need to do a REV instruction
after the load. It seems better to use LD1RQ[BHW] on a 128-bit
pattern instead, since that gets the endianness right without
a separate fixup instruction.

The simplest fix seemed to be to use the LD1RQ appropriate for the

This helps to fix some of the sve/slp_*.c tests for aarch64_be,
although a later patch is needed as well.

[AArch64] Generalise aarch64_simd_valid_immediate for SVE
The current aarch64_simd_valid_immediate code predates the move
to the new CONST_VECTOR representation, so for variable-length SVE
it only handles duplicates of single elements, rather than duplicates
of repeating patterns.
This patch removes the restriction. It means that the validity
of a duplicated constant depends only on the bit pattern, not on
the mode used to represent it.
The patch is needed by a later big-endian fix.

[AArch64] Tighten aarch64_secondary_reload condition (PR 83845)
aarch64_secondary_reload enforced a secondary reload via
aarch64_sve_reload_be for memory and pseudo registers, but failed
to do the same for subregs of pseudo registers. To avoid this and
any similar problems, the patch instead tests for things that the move
patterns handle directly; if the operand isn't one of those, we should
use the reload pattern instead.
The patch fixes an ICE in sve/mask_struct_store_3.c for aarch64_be,

[AArch64] PR tree-optimization/64946: XFAIL gcc.target/aarch64/vect-abs-compile.c
