llvm-capstone/clang/www/cxx_dr_status.html
Richard Smith ee0ce302c5 Refactor constant evaluation of typeid(T) to track a symbolic type_info 
object rather than tracking the originating expression.

This is groundwork for supporting polymorphic typeid expressions. (Note
that this somewhat regresses our support for DR1968, but it turns out
that that never actually worked anyway, at least in non-trivial cases.)

This reinstates r360974, reverted in r360988, with a fix for a
static_assert failure on 32-bit builds: force Type base class to have
8-byte alignment like the rest of Clang's AST nodes.
