\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Scan the MachineFunction for DBG_VALUE instructions, and replace them with a data structure similar to LiveIntervals. The live range of a DBG_VALUE is determined by propagating it down the dominator tree until a new DBG_VALUE is found. When a DBG_VALUE lives in a register, its live range is confined to the live range of the register's value. LiveDebugVariables runs before coalescing, so DBG_VALUEs are not artificially extended when registers are joined. The missing half will recreate DBG_VALUE instructions from the intervals when register allocation is complete. The pass is disabled by default. It can be enabled with the temporary command line option -live-debug-variables. llvm-svn: 120636
*	Stub out a new LiveDebugVariables pass.	Jakob Stoklund Olesen	2010-11-30	1	-0/+50
	This analysis is going to run immediately after LiveIntervals. It will stay alive during register allocation and keep track of user variables mentioned in DBG_VALUE instructions. When the register allocator is moving values between registers and the stack, it is very hard to keep track of DBG_VALUE instructions. We usually get it wrong. This analysis maintains a data structure that makes it easy to update DBG_VALUE instructions. llvm-svn: 120385
