This adds -no-opaque-pointers to clang tests whose output will change when opaque pointers are enabled by default. This is intended to be part of the migration approach described in https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9. The patch has been produced by replacing %clang_cc1 with %clang_cc1 -no-opaque-pointers for tests that fail with opaque pointers enabled. Worth noting that this doesn't cover all tests, there's a remaining ~40 tests not using %clang_cc1 that will need a followup change. Differential Revision: https://reviews.llvm.org/D123115
