Andrew Trick 113bebb035 Centralize logic for access marker and exclusivity verification. ...

Create helpers in InstructionUtils.h wherever we need a guarantee that the diagnostics cover the same patterns as the verifier. Eventually this will be called from both SILVerifier and the diagnostic pass:
- findAccessedAddressBase
- isPossibleFormalAccessBase
- isPartialApplyOfReabstractionThunk
- findClosureForAppliedArg
- visitAccessedAddress

Add partial_apply verification assert.

This applies the normal "find a closure" logic inside the "find all partial_apply uses" verification. Making the verifier round-trip ensures that we don't have holes in exclusivity enforcement related to this logic.
