to properly enable the extensions being tested on the llvm-mc command
line before validating that the directive correctly disables them.

AArch64 does not support enabling rcpc via .arch_extension in assembly.
GCC, on the other hand, does.
This patch adds 'rcpc' as a valid value to .arch_extension handling.

This patch fixes .arch_extension directive parsing to handle a wider
range of architecture extension options. The existing parser was parsing
extensions as an identifier which breaks for extensions containing a
"-", such as the "tlb-rmi" extension.
The extension is now parsed as a string. This is consistent with the
extension parsing in the .arch and .cpu directive parsing.
