[PATCH] D23630: [PPC] Expand ISEL instruction into if-then-else sequence

[Tony Jiang via Phabricator via llvm-commits]

jtony added a comment.

The total SPEC statistics:

Expanded 23601
==============

For these ISEL with same CR (just compare operand(3), it is still possible CR can be modified in between the two ISELs, and the registers used or defined by the later ISEL could also be changed) :

1. Contiguous 825
2. Non-Contiguous 2618

Also, this patch doesn't address the option comment by Hal.
