Log:
Move setTargetAttributes after setGVProperties in SetFunctionAttributes

AMDGPU currently relies on global properties being set before
setTargetProperties is called. Existing targets like MIPS which rely on
setTargetProperties do not rely on the current behavior, so this patch
moves the call later in SetFunctionAttributes.
