Work through several issues with LBOUND() and UBOUND() of ASSOCIATE construct entities that have been associated with named constants or subobjects of named constants that are sporting non-default lower bounds. Sometimes the non-default lower bounds matter, sometimes they don't. Add a fairly exhaustive test to work through the possibilities. Differential Revision: https://reviews.llvm.org/D156756

! lower bounds expose those bounds to LBOUND()/UBOUND(), sometimes

! they do not.
