[PATCH] D106299: [Local] Flag to decide if a trap should be placed before unreachable

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

I think `TrapBeforeUnreachableChoice` should be a TTI hook, overrided by GPU targets.
I think `shouldUseTrapBeforeUnreachable()` should be sunk into `changeToUnreachable()`, and `UseLLVMTrap` renamed into `PreferToUseLLVMTrap`, with an appropriate documentation opdate.
