    M llvm/test/Transforms/SpeculativeExecution/PR46267.ll

  Log Message:
  -----------
  SpeculativeExecution: Fix for logic change introduced in D81730.

Summary:
The test case started to hoist bitcasts to upper BB after D81730.
Reverted unintentional logic change. Some instructions may have zero cost but
will not be hoisted by different limitation so should be counted for threshold.
