[PATCH] D48674: SelectionDAGBuilder, mach-o: Skip trap after noreturn call (for Mach-O)

[David Blaikie via llvm-commits]

This feature was/is only enabled in -O0, though, right? As a debugging aid,
if I recall correctly - because it can be super confusing when your code
falls off the end of one function into the next. Is the code size savings
(only at O0) worth the increased cost to debug?
