[PATCH] D29107: Fix a bug when unswitching on partial LIV for SwitchInst

[Xin Tong via Phabricator via llvm-commits]

trentxintong added a comment.

Decided to teach how to unswitch value out of default-case in case its can lead to
simplifications in at least one of the loops.

Also fix a small bug about how unswitched value is recorded. Updated the test cases to
check for that.
