Summary: This change enables frame pointer elimination in non-leaf functions. The -fomit-frame-pointer option still needs to be used when compiling via clang (or an equivalent method of not setting the 'no-frame-pointer-elim*' function attributes if generating llvm IR via some other method) to take advantage of this optimization. This change should be NFC when compiling via clang without -fomit-frame-pointer.
