Most tests are either compfailing or runfailing.
They should start passing once we start using ATTACH map-type based
codegen. (#153683)
Even after they start passing, there are a few places where the EXPECTED
and actual CHECKs are different, due to two main issues:
* use_device_ptr translation on `&p[0]` is not succeeding in looking-up
a previously mapped `&p[1]`
* privatization of byref use_device_addr operands is not happening
correctly.
The above should be fixed as separate standalone changes.
