Add module flags metadata to record the settings for enum and wchar width Add module flags metadata to record the settings for enum and wchar width, to allow correct ARM build attribute generation llvm-svn: 211354

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
