The above patch will handle the fallouts of this Clang patch, including some changes to un-duplicate work that RewriteAsmDirectives.cpp does. The goal of this patch is to force some extra ordering on non-atomics for le32 which LLVM doesn't necessarily provide.

Without fmath-errno, Clang currently generates calls to @llvm.pow.* intrinsics when it sees pow*(). This may not be suitable for all targets (for example le32/PNaCl), so the attached patch adds a target hook that CodeGen queries. The target can state its preference for having or not having the intrinsic generated. Non-PNaCl behavior remains unchanged; PNaCl-specific test added.

This is a LOCALMOD for now, but I'm working on a more generic solution that can be upstreamed to Clang.
