Slava Pestov 68bdfa81e3 SILGen: Fix verifier error when forming keypath to subscript with resilient index type ...

emitKeyPathSubscriptOperands() uses the ArgEmitter to collect
index arguments, which uses ResilienceExpansion::Minimal when
lowering parameter types.

For this reason, lowerKeyPathSubscriptIndexTypes() should also
use ResilienceExpansion::Minimal when lowering parameter types.

Otherwise, we crash in the SIL verifier due to a loadable vs
address-only mismatch, if the index type is resilient.
