If a module has function references, but no functions themselves, we may end up never calling runOnMachineFunction and therefore would never initialize nvptxSubtarget field which would eventually cause a crash. Instead of relying on nvptxSubtarget being initialized by one of the methods, retrieve subtarget info directly. Differential Revision: https://reviews.llvm.org/D55580 llvm-svn: 348952
