[AArch64] Fix SVE testsuite failures for ILP32 (PR 83846)

[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.)
