Initialize AsmPrinter::MF in the constructor
MF is normally initialized in AsmPrinter::SetupMachineFunction, but if the file contains only globals (no functions), then we need this to be initialized because, when encountering an error, lowerConstant() references it. This should fix the non-deterministic failures of test/CodeGen/X86/nonconst-static-iv.ll, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186068 91177308-0d34-0410-b5e6-96231b3b80d8
