static

ReplaceUsesOfNonProtoTypeWithRealFunction - This function is called when we implement a function with no prototype, e.g.

"int foo() {}". If there are existing call uses of the old function in the module, this adjusts them to call the new function directly.

This is not just a cleanup: the always_inline pass requires direct calls to functions to be able to inline them. If there is a bitcast in the way, it won't inline them. Instcombine normally deletes these calls, but it isn't run at -O0.
