Bill Wendling 929b90ff32 Clean up the handling of an EBP/RBP unwind frame pointer. In particular, don't 
assert when the frame pointer is -1 (i.e., the function is "frameless").

Still to do: "frameless" unwind information.

Bill Wendling 667be58220 Use ArrayRef instead of a std::vector&.

Charles Davis 7ed40cbded Put FrameSetup flag on x86 instructions that set up the call frame. No 
functionality change.

Later on, we'll use the flag to emit SEH pseudo-ops that describe how the
call frame was built.

Rafael Espindola fc9bae6f8b Replace the -unwind-tables option with a per function flag. This is more 
LTO friendly as we can now correctly merge files compiled with or without
-fasynchronous-unwind-tables.

Rafael Espindola 80cb3cb1d6 Print all the moves at a given label instead of just the first one. 
Remove previous DwarfCFI hack.

Rafael Espindola a01cdb0e37 Add 129518 back with a fix for when we are producing eh just because of debug info. 
Change ELF systems to use CFI for producing the EH tables. This reduces the
size of the clang binary in Debug builds from 690MB to 679MB.

NAKAMURA Takumi 521eb7c11e Target/X86: [PR8777][PR8778] Tweak alloca/chkstk for Windows targets. 
FIXME: Some cleanups would be needed.

NAKAMURA Takumi d4e5003a3f Target/X86: Always emit "push/pop GPRs" in prologue/epilogue and emit "spill/reload frames" for XMMs. 
It improves Win64's prologue/epilogue but it would not affect ia32 and amd64 (lack of nonvolatile XMMs).
