swift234

When demangling as string type names that come from module names of the form __lldb_expr_<something> in a Swift program, hide the module
The __lldb_expr modules are special as in they are autogenerated by LLDB and meant to not be user-accessible, so showing them adds visual noise for no user benefit

I am open to the notion of adding a flag to swift-demangle to the same effect, but that seems much lower priority
