*	Added optimization that narrow load / op / store and the 'op' is a bit ↵	Evan Cheng	2009-05-28	1	-0/+23
	twiddling instruction and its second operand is an immediate. If bits that are touched by 'op' can be done with a narrower instruction, reduce the width of the load and store as well. This happens a lot with bitfield manipulation code. e.g. orl $65536, 8(%rax) => orb $1, 10(%rax) Since narrowing is not always a win, e.g. i32 -> i16 is a loss on x86, dag combiner consults with the target before performing the optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72507 91177308-0d34-0410-b5e6-96231b3b80d8
