Slava Pestov 57b702be07 ASTDemangler: Fix round-tripping of SILBoxTypeWithLayout ...

The more awkward setup with pushGenericParams()/popGenericParams()
is required so that when demangling requirements and field types
we get the correct pack-ness for each type parameter. The pack-ness
is encoded as part of the generic signature, and not as part of
the type parameter mangling itself.

Fixes the ASTDemangler issue from rdar://problem/115459973.
