[MachineOutliner] Check for explicit uses of LR/W30 in MI operands Before, the outliner would grab ADRPs that used LR/W30. This patch fixes that by checking for explicit uses of those registers before the special-casing for ADRPs. This also adds a test that ensures that those sorts of ADRPs won't be outlined. llvm-svn: 330783

[Alignment] Use llvm::Align in MachineFunction and TargetLowering - fixes mir parsing Summary: This catches malformed mir files which specify alignment as log2 instead of pow2. See https://reviews.llvm.org/D65945 for reference, This is patch is part of a series to introduce an Alignment type.
