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.

Ignore top-level qualifiers in casts, which fixes issues in reinterpret_cast.
This rule comes from [expr.type]/8.2.2 which explains that casting to a
pr-qualified type should actually cast to the unqualified type. In C++
this is only done for types that aren't classes or arrays.
