Re-apply r211399, "Generate native unwind info on Win64" with a fix to ignore SEH pseudo ops in X86 JIT emitter. -- 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.

X86: Emit an ABI compliant prologue and epilogue for Win64 Win64 has specific contraints on what valid prologues and epilogues look like. This constraint is born from the flexibility and descriptiveness of Win64's unwind opcodes. Prologues previously emitted by LLVM could not be represented by the unwind opcodes, preventing operations powered by stack unwinding to successfully work.
