7b06b7357a Add a parameter to the Win64 EH section getters to get a section with a 
suffix (e.g. .xdata$myfunc). The suffix part isn't implemented yet, but
I'll get to it in the next patch.

Fix up all callers of the affected functions. Make them pass said suffix to
the function.

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.

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.

321fe74b2d A handler for a function in the Win64 EH scheme can be both an unwind handler 
and an exception handler. Handle that case.

Also, add an 'Emitted' member to the MCWin64EHUnwindInfo struct. It will be
needed later.

c3b162857a Implement the Win64 EH prolog instruction methods on the base MCStreamer. 
I had to change the API slightly to avoid overloading issues.

440596ffe5 Turns out GAS does have Win64 EH directives. (It also supports WinCE EH.) Make 
ours compatible with GAS.

In retrospect, I should have emailed binutils about this earlier. Thanks to
Kai Tietz for pointing out that GAS already had SEH directives.

fa89218a43 Fix build issues with headers, which I discovered by actually using them. 
Also, convert all the inline functions on UnwindInfo into methods.

f0542c07f7 Add a header patterned after MCDwarf.h for supporting Win64 exception handling 
under MC.
