6035a9f12a Revert "CodeGen: Allow small copyable blocks to "break" the CFG." 
This reverts commit ada6595a526d71df04988eb0a4b4fe84df398ded.

This needs a simple probability check because there are some cases where it is
not profitable.

af32417840 CodeGen: Allow small copyable blocks to "break" the CFG. 
When choosing the best successor for a block, ordinarily we would have preferred
a block that preserves the CFG unless there is a strong probability the other
direction. For small blocks that can be duplicated we now skip that requirement
as well.

fc40b8c4ea [X86] Mark pseudo instruction TEST8ri_NOEREX as hasSIdeEffects=0. 
Also, add a case clause in X86InstrInfo::shouldScheduleAdjacent to enable
macro-fusion.
