Features: Fix the default C dialect for Clang and GNU. Clang 3.4 uses C99 by default, and Clang 3.6 uses C11 by default: http://thread.gmane.org/gmane.comp.compilers.clang.devel/39379 GNU 4.9 uses C90 by default, and GNU 5.0 uses C11 by default: https://gcc.gnu.org/gcc-5/changes.html Test that the default compiler settings result in the expected dialect macros being defined for both C and CXX. Remove the unused main.c file from the CompileFeatures unit test.

#if DEFAULT_C11
Tests: Make CompileFeatures C dialect check consistent with impl `Modules/CMakeCCompilerId.c.in` will report the C dialect as 11 whenever `__STDC_VERSION__` indicates *at least* C 11. Make the test consistent with this. We already do this for the C++ case. Fixes: #17740

Revise C++ coding style using clang-format Run the `Utilities/Scripts/clang-format.bash` script to update all our C++ code to a new style defined by `.clang-format`. Use `clang-format` version 3.8. * If you reached this commit for a line in `git blame`, re-run the blame operation starting at the parent of this commit to see older history for the content. * See the parent commit for instructions to rebase a change across this style transition commit.
