Semantically revert r236031, which is not a good idea for in-order targets.

At the least it should be guarded by some kind of target hook.
It also introduced catastrophic compile time and code quality
regressions on some out of tree targets (test case still being
reduced/sanitized).

Sanjay agreed with reverting this patch until these issues can be
resolved.
