------------------------------+---------------------------------------------
The `-msse<version>` flag can be used to have the native and LLVM backends
emit SSE instructions. Since a Haskell project might contain C code in
addition to Haskell code and since that code usually goes through ghc
(which calls gcc) it would be nice if ghc forwarded the `-msse` flag when
it invokes the C compiler, so the latter can use SSE instructions as well.
While this is possible today by using `-optC` it would be nice if the user
doesn't have to remember to pass this flag in addition to `-msse`.
