Hi, @jrtc27

About the concern the invalid combination RV32 + zprvsfextra on riscv attribute, 
I upload a patch D108189 <https://reviews.llvm.org/D108189> based on @kito-cheng 's patch D105168 <https://reviews.llvm.org/D105168> to forbid emitting rv32+zprvsfextra  arch string.
And It also deny to accept `rv32izprvsfextra` https://reviews.llvm.org/differential/changeset/?ref=2787775.

Patch D108189 <https://reviews.llvm.org/D108189> have not emitted and accepted invalid arch string combined from rv32 and  zprvsfextra.

Thanks for feedback.
