Benjamin Kramer ccd492c9d6 LCSSA: Try to recover compile time regressions due to SCEV updates.
- Use value handle tricks to communicate use replacements instead of forgetLoop, this is a lot faster.
- Move the "big hammer" out of the main loop so it's not called for every instruction.

This should recover most (if not all) compile time regressions introduced by this code.
