NVPTX/dont-introduce-addrspacecast.ll required manually removing a check for a bitcast. AArch64/combine-address-mode.ll required rerunning update_test_checks Mips required some manual updates due to a CHECK-NEXT coming after a deleted bitcast. ARM/sink-addrmode.ll needed one small manual fix. Excludes one X86 function which needs more attention.
