Geoff Berry 5a77517c7c [AArch64] Enable non-leaf frame pointer elimination.
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.
