Jeremy Morse 92aec5192c [DebugInfo][RemoveDIs] Use iterator-inserters in clang (#102006) ...

As part of the LLVM effort to eliminate debug-info intrinsics, we're
moving to a world where only iterators should be used to insert
instructions. This isn't a problem in clang when instructions get
generated before any debug-info is inserted, however we're planning on
deprecating and removing the instruction-pointer insertion routines.

Scatter some calls to getIterator in a few places, remove a
deref-then-addrof on another iterator, and add an overload for the
createLoadInstBefore utility. Some callers passes a null insertion
point, which we need to handle explicitly now.
