[AArch64] Rewrite aarch64_simd_valid_immediate

This patch reworks aarch64_simd_valid_immediate so that
it's easier to add SVE support.  The main changes are:

- make simd_immediate_info easier to construct
- replace the while (1) { ... break; } blocks with checks that use
  the full 64-bit value of the constant
- treat floating-point modes as integers if they aren't valid
  as floating-point values
