[LoopPred] Selectively disable to preserve test cases

I'm about to enable the new loop predication transform by default.  It has the effect of completely destroying many read only loops - which happen to be a super common idiom in our test cases.  So as to preserve test coverage of other transforms, disable the new transform where it would cause sharp test coverage regressions.

(This is semantically part of the enabling commit.  It's committed separate to ease revert if the actual flag flip gets reverted.)
