Fangrui Song f4b25f700a [ConstantHoisting] Call cleanup() in ConstantHoistingPass::runImpl to avoid dangling elements in ConstIntInfoVec for new PM ...

Summary:
ConstIntInfoVec contains elements extracted from the previous function.
In new PM, releaseMemory() is not called and the dangling elements can
cause segfault in findConstantInsertionPoint.

Rename releaseMemory() to cleanup() to deliver the idea that it is
mandatory and call cleanup() in ConstantHoistingPass::runImpl to fix
this.
