Patrick O'Neill fcad2bbcfc [RISC-V] Add proposed mapping for Ztso ...

Currently LLVM emits Ztso code for fences, loads, and stores (behind an
experimental flag) [1]. This patch updates the mapping and implements
support for LR/SC and AMO ops. This updated mapping is compatible with
the RVWMO ABI present in the psABI. Additional context can be found in
the psABI pull request [2].
