  Changed paths:

    M llvm/include/llvm/Support/RISCVISAInfo.h
    M llvm/lib/Support/RISCVISAInfo.cpp

  Log Message:
  -----------
  [RISCV] Use a lambda to avoid having the Support library depend on Option library.

RISCVISAInfo::toFeatures needs to allocate strings using
ArgList::MakeArgString, but toFeatures lives in Support and
MakeArgString lives in Option.

toFeature only has one caller, so the simple fix is to have that
caller pass a lamdba that wraps MakeArgString to break the
dependency.
