Subject: Bugfix for PR17099: Wrong cast operation. MergeFunctions emits
 Bitcast instead of pointer-to-integer operation. Patch fixes
 MergeFunctions::writeThunk function. It replaces unconditional Bitcast
 creation with "Value* createCast(...)" method, that checks operand types and
 selects proper instruction. See unit-test as example.
