Summary: Also fixup rL371928 for cases that occur on our out-of-tree backend There were still quite a few intermediate APInts and this caused the compile time of MCCodeEmitter for our target to jump from 16s up to ~5m40s. This patch, brings it back down to ~17s by eliminating pretty much all of them using two new APInt functions (extractBitsAsZExtValue(), insertBits() but with a uint64_t). The exact conditions for eliminating them is that the field extracted/inserted must be <=64-bit which is almost always true. Note: The two new APInt API's assume that APInt::WordSize is at least 64-bit because that means they touch at most 2 APInt words. They statically assert that's true. It seems very unlikely that someone is patching it to be smaller so this should be fine.
