Use -ffreestanding with clang_cc1 to make the test picks the clang builtin include. llvm-svn: 135766

Driver: hoist the `wchar_t` handling to the driver Move the logic for determining the `wchar_t` type information into the driver. Rather than passing the single bit of information of `-fshort-wchar` indicate to the frontend the desired type of `wchar_t` through a new `-cc1` option of `-fwchar-type` and indicate the signedness through `-f{,no-}signed-wchar`. This replicates the current logic which was spread throughout Basic into the `RenderCharacterOptions`. Most of the changes to the tests are to ensure that the frontend uses the correct type. Add a new test set under `test/Driver/wchar_t.c` to ensure that we calculate the proper types for the various cases. llvm-svn: 315126

Prior to adding the new "expected-no-diagnostics" directive to VerifyDiagnosticConsumer, make the necessary adjustment to 580 test-cases which will henceforth require this new directive. llvm-svn: 166280

Add a missing test for the limits on wchar llvm-svn: 135708

Remove WCHAR_MIN and WCHAR_MAX from limits.h. According to posix and c99 these should be in stdint.h - and they already are. Fixes rdar://10097036. llvm-svn: 139332
