    M llvm/unittests/TargetParser/RISCVISAInfoTest.cpp

  Log Message:
  -----------
  [RISCV] Add partial validation of S and X extension names to RISCVISAInfo::parseNormalizedArchString.

Extensions starting with 's' or 'x' should always be followed by an
alphabetical character.  I don't know of any crashes from this currently,
but it seemed better to be defensive.
