[AArch64] Removed unnecessary copy patterns with v1fx types.

- Copy patterns with float/double types are enough.
- Fix typos in test case names that were using v1fx.
- There is no ACLE intrinsic that uses v1f32 type.  And there is no conflict of
  neon and non-neon ovelapped operations with this type, so there is no need to
  support operations with this type.
- Remove v1f32 from FPR32 register and disallow v1f32 as a legal type for
  operations.
