7e6e4dd058 Re-apply bottom-up fast-isel, with fixes. Be very careful to avoid emitting
a DBG_VALUE after a terminator, or emitting any instructions before an EH_LABEL.

Debug info intrinsics win for now.

d0caefa601 Implement bottom-up fast-isel. This has the advantage of not requiring
a separate DCE pass over MachineInstrs.

8022d8e885 Teach fast-isel to avoid loading a value from memory when it's already
available in a register. This is pretty primitive, but it reduces the
number of instructions in common testcases by 4%.
