Fix several things so that vector instructions work correctly with strict FP:

- In clang generate fcmps when appropriate for neon intrinsics
- Fix legalization of scalarized strict FP vector operations
- Add some missing strict FP handling to AArch64TargetLowering
- Adjust the aarch64-neon-intrinsics-constrained.c clang test to expect the right output and un-XFAIL it.
