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.

Features: Update the default_dialect test for old GNU-like compilers. Prior to GNU 4.7, GNU defined __cplusplus incorrectly, and defined __GXX_EXPERIMENTAL_CXX0X__ in C++11 mode.
