David Spickett 0b8a44388e [llvm][AArch64] Explain why certain registers are reserved on Arm64EC
This extends 4658366d95 to add a note
explaining why the register is reserved.

note: x13 is clobbered by asynchronous signals when using Arm64EC.

I've added testing for w/x registers and v/q/s/d and h floating point
registers.

llvm will accept, but silently do nothing with, b registers. So they
are not tested here (clang rejects them so at least for C you're safe anyway).
