Use '%clang_cc1' instead of '%clang' to make the warning output more consistent across platforms (for this test). llvm-svn: 100827

Keep track of when declarations are "used" according to C and C++. This logic is required to trigger implicit instantiation of function templates and member functions of class templates, which will be implemented separately. This commit includes support for -Wunused-parameter, printing warnings for named parameters that are not used within a function/Objective-C method/block. Fixes <rdar://problem/6505209>. llvm-svn: 73797

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. llvm-svn: 137910
