clang-p2996/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp
Jakob Stoklund Olesen 9a624fa993 Collect and coalesce DBG_VALUE instructions before emitting the function. 
Correctly terminate the range of register DBG_VALUEs when the register is
clobbered or when the basic block ends.

The code is now ready to deal with variables that are sometimes in a register
and sometimes on the stack. We just need to teach emitDebugLoc to say 'stack
slot'.
