[llvm] r211543 - [FastISel][X86] Optimize selects when the condition comes from a compare.

[Juergen Ributzka]

Hi Stephane,

I will take a look and see if I can find a quick fix. If not, I will revert the change.

Thanks for tracking this down for me again. Are you running an -O0 buildbot?

Cheers,
Juergen
