[Demangler] Tidy up a bit, and add line numbers to ManglingErrors.

Browse Source 
Because DEMANGLER_ASSERT() might cause the remanglers to return a ManglingError
with the code ManglingError::AssertionFailed, it's useful to have a line number
in the ManglingError as well as the other information.  This is also potentially
helpful for other cases where the code is used multiple times in the remanglers.
