Implement '-Weverything', which enables all warnings except those explicitly mapped to be ignored.
Currently this includes -pedantic warnings as well; we'll need to consider whether these should
be included.
This works as expected with -Werror.
Test cases were added to Sema/warn-unused-parameters.c, but they should probably be broken off into
their own test file.
