Chandler Carruth f3bd8ddedb Revert r301950: SpeculativeExecution: Stop using whitelist for costs 
This pass doesn't correctly handle testing for when it is legal to hoist
arbitrary instructions. The whitelist happens to make it safe, so before
it is removed the pass's legality checks will need to be enhanced.

Details have been added to the code review thread for the patch.

Just let TTI's cost do this instead of arbitrarily restricting
this.
