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'. llvm-svn: 128327
