[Patch AArch64 docs] Document the RcPc extension

[Patch AArch64 docs] Document the RcPc extension

Hi,

Andrew pointed out that I did not document the new architecture extension
flag I added the RcPc iextension. This was intentional, as enablihg the rcpc
extension does not change GCC code generation, and is just an assembler flag.
But for completeness, here is documentation for the new option.

OK?

Thanks,
James
