[sil-linker] Improve the implementation of the hasSILFunction API

Browse Source 
It it now possible to check if a function with a given name and a given linkage exists in one of the modules,
even if the current module contains a function with this name but a difference linkage.
This is useful e.g. for performing a lookup of pre-specializations.
