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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137910 91177308-0d34-0410-b5e6-96231b3b80d8
