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. Fixes: PR49221 Reviewed By: Anastasia Differential Revision: https://reviews.llvm.org/D102689
