Fixes an assertion failure when creating RTTI descriptors for types with top-level qualifiers (const, volatile, etc.). The Itanium C++ ABI requires that RTTI descriptors be created for unqualified types only, but ClangIR was passing qualified types to the mangling function. The fix strips qualifiers in BuildTypeInfo before mangling, matching the behavior of traditional CodeGen. Also strips qualifiers when getting RTTI descriptors for dynamic_cast operands, consistent with CodeGen's implementation. This fixes std::regex usage and other cases where qualified types are used with typeid or dynamic_cast. ghstack-source-id: 3c9ffe9 Pull-Request: #2002

Fixes an assertion failure when creating RTTI descriptors for types
with top-level qualifiers (const, volatile, etc.). The Itanium C++ ABI
requires that RTTI descriptors be created for unqualified types only,
but ClangIR was passing qualified types to the mangling function.
The fix strips qualifiers in BuildTypeInfo before mangling, matching
the behavior of traditional CodeGen. Also strips qualifiers when
getting RTTI descriptors for dynamic_cast operands, consistent with
CodeGen's implementation.
This fixes std::regex usage and other cases where qualified types
are used with typeid or dynamic_cast.
