[llvm-dev] Stack maps on AArch64

[Rob Lyerly via llvm-dev]

I figured out the issue -- the AArch64 backend only emits the stack map
section if isOSBinFormateMachO() returns true -- see [1], lines 123 - 134.
Moving the call to serializeToStackMapSection() outside of the conditional
fixes the problem.
