Rafael Espindola f28213ca01 Don't print an unused label before .cfi_endproc.

Rafael Espindola 382412032c Don't print a label before .cfi_startproc when we don't need to. This makes 
the produce assembly when using CFI just a bit more readable.

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'.
