DBG_INSTR_REF's and DBG_VALUE's can end up in blocks that aren't in the lexical scope of their variable. It's arguable as to what we should do about this, however VarLocBasedLDV permits such variable locations to be propagated, so let's allow it in InstrRefBasedLDV. It's necessary for the modified test to work. Differential Revision: https://reviews.llvm.org/D114578
