Ahmed Bougacha 0d77054e90 [GlobalISel] Don't select trivially dead instructions. ... Folding instructions when selecting can cause them to become dead. Don't select these dead instructions (if they don't have other side effects, and don't define physical registers). Preserve existing tests by adding COPYs. In some tests, the G_CONSTANT vregs never get constrained to a class: the only use of the vreg was folded into another instruction, so the G_CONSTANT, now dead, never gets selected. llvm-svn: 298224		2017-03-19 16:13:00 +00:00
