-- This patch enables LLVM to emit Win64-native unwind info rather than DWARF CFI. It handles all corner cases (I hope), including stack realignment. Because the unwind info is not flexible enough to describe stack frames with a gap of unknown size in the middle, such as the one caused by stack realignment, I modified register spilling code to place all spills into the fixed frame slots, so that they can be accessed relative to the frame pointer.
