[PATCH] [CodeGenPrepare] Teach when it is profitable to speculate calls to @llvm.cttz/ctlz.

[Andrea Di Biagio]

Thanks for the review Hal!

I modified the patch so that ModifiedDT is set to true when this new transformation fires.
I also removed the TODO comments in X86ISelLowering.cpp as suggested by Chandler.
Committed revision 224899.
