  llvm-reduce: Fix assert if call type mismatches function type

This fixes asserting on IR with undefined behavior from calls
with a type that does not match the type of the target function.

Just ignore callsites which already didn't match the function
signature. This is the most straightforward fix, the reference
to the global will be replaced later anyway. A better implementation
would try to pad out unused arguments, particularly in the cases where
the signatures only differ in type and not count.

Fixes #69312
