When two interposable functions are merged, we cannot replace uses and have to emit calls to a common internal function. However, writeThunk() will not actually emit a thunk if the function is too small. This leaves us in a broken state where mergeTwoFunctions already rewired the functions, but writeThunk doesn't do anything. This patch changes the implementation so that: * writeThunk() does just that. * The direct replacement of calls is moved into mergeTwoFunctions() into the non-interposable case only. * isThunkProfitable() is extracted and will be called for the non-iterposable case always, and in the interposable case only if uses are still left after replacement. This issue has been introduced in https://reviews.llvm.org/D34806, where the code for checking thunk profitability has been moved.
