[clang] [RISC-V] Add validation for inline assembly constraints

Authored by mhorne on Apr 24 2019, 3:14 PM.



GCC supports a small number of RISC-V specific inline assembly
constraints, while currently clang only supports the machine independent
ones for RISC-V targets. Add parsing for these constraints, based on
their descriptions in the GCC documentation [1].

Apologies if I didn't tag the right reviewers; I took a look at those who seemed to be most involved with the RISC-V target, but if there's anyone more appropriate to review clang changes then feel free to add them instead :)

This has been handled more correctly and completely with recent patches.
