	only run for x86 with fastisel. I've found it being very effective in eliminating some obvious dead code as result of formal parameter lowering especially when tail call optimization eliminated the need for some of the loads from fixed frame objects. It also shrinks a number of the tests. A couple of tests no longer make sense and are now eliminated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95493 91177308-0d34-0410-b5e6-96231b3b80d8

	instruction. If done, the instruction does a 64-bit load and that's not safe. This can happen we a subreg_to_reg 0 has been coalesced. One exception is when the instruction that folds the load is a move, then we can simply turn it into a 32-bit load from the stack slot. rdar://7170444 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81494 91177308-0d34-0410-b5e6-96231b3b80d8
