07cbe23173 Assorted fixes for Win64 EH unwind info emission: 
- Flip order of bitfields. This gets our output matching GAS.
- Handle case where the end of the prolog wasn't specified.
- If the resulting unwind info struct is less than 8 bytes, pad to 8 bytes.

Add a test for the latter two.

c4cbf9b6aa Start keeping track of where the various unwind instructions are in the prolog. 
Use them to calculate the offset inside the prolog. Emit this value when
emitting the unwind codes.

ef60724ddc Add missing break statements. Align UNWIND_INFO and RUNTIME_FUNCTION structs 
to 4 bytes.

I'm surprised no one caught the missing break statements.

38ea9eecd7 Implement emission of all Win64 exception tables. Make the COFF streamer emit 
these tables.

3185f5c353 Make the COFF streamer emit unwind info when processing a .seh_handlerdata 
directive.

Implement emission of Win64 EH unwind info.

Pull in <cassert> in MCWin64EH.h so it can use the assert() macro.
