Suppress warning in rust-ast-lower-type.h ASTLowerGenericParam.visit.
Translating the AST LifetimeType to the HIR LifetimeType causes a warning:
warning: ‘ltt’ may be used uninitialized
Add a default clause to the switch statement calling gcc_unreachable.
This will suppress the warning and make sure that if the AST lifetime type
is invalid or a new unknown type we immediately know when lowering the AST.
