[NFC] Pass a reference to CodeGenFunction to methods of LValue and

AggValueSlot

This reapplies 8a5b7c35709d9ce1f44a99f0c5b084bf2696ea17 after a null
dereference bug in CGOpenMPRuntime::emitUserDefinedMapper.

Original commit message:

This is needed for the pointer authentication work we plan to do in the
near future.
