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. llvm-svn: 190859

Don't merge tiny functions. It's silly to merge functions like these: define void @foo(i32 %x) { ret void } define void @bar(i32 %x) { ret void } to get define void @bar(i32) { tail call void @foo(i32 %0) ret void } llvm-svn: 191786
