*	Run LiveVariables instead of computing liveness locally in -regalloc=fast.	Jakob Stoklund Olesen	2010-04-21	1	-177/+2
\| \| \| \| \| \| \| \| \| \| \|	This actually makes everything slower, but the plan is to have isel add <kill> flags the way it is already adding <dead> flags. Then LiveVariables can be removed again. When ignoring the time spent in LiveVariables, -regalloc=fast is now twice as fast as -regalloc=local. llvm-svn: 102034
*	Add fast register allocator, enabled with -regalloc=fast.	Jakob Stoklund Olesen	2010-04-21	1	-0/+1107
	So far this is just a clone of -regalloc=local that has been lobotomized to run 25% faster. It drops the least-recently-used calculations, and is just plain stupid when it runs out of registers. The plan is to make this go even faster for -O0 by taking advantage of the short live intervals in unoptimized code. It should not be necessary to calculate liveness when most virtual registers are killed 2-3 instructions after they are born. llvm-svn: 102006
