Log:
[AArch64] Fix predicate alignment for fixed-length SVE

aarch64_simd_vector_alignment was only giving predicates 16-bit
alignment in VLA mode, not VLS mode.  I think the problem is latent
because we can't yet create an ABI predicate type, but it seemed worth
fixing in a standalone patch rather than as part of the main ACLE series.

The ACLE patches have tests for this.

gcc/
	* config/aarch64/aarch64.c (aarch64_simd_vector_alignment): Return
	16 for SVE predicates even if they are fixed-length.
