LOG: [IR][NFC] Remove unused helpers for inserting dbg intrinsics (#212304)

As a result of the almost complete transition from debug intrinsics to
debug records, a few functions are now unused in the public API. This
patch removes those.

Added: 
    

Modified: 
    llvm/include/llvm/IR/DIBuilder.h
    llvm/lib/IR/DIBuilder.cpp

Removed:
