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.)

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.

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:

                               +-----+-----+-----+-----+-----+----

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

a separate fixup instruction.

The fallback way of handling a repeated 128-bit constant vector for SVE
is to force the 128 bits to the constant pool and use LD1RQ to load it.
Previously the code always used the byte variant of LD1RQ (LD1RQB),
with a preceding BSWAP for big-endian targets.  However, that BSWAP
doesn't handle all cases correctly.

The simplest fix seemed to be to use the LD1RQ appropriate for the
element size.

This helps to fix some of the sve/slp_*.c tests for aarch64_be,
