Stephen Kelly a60027a642 Features: Ensure appropriate return value from feature test macros.
GNU-CXX already has complex logic and sets the _result to 0 before
tests which may set it to something else.

Change the other modules to be consistent with that.

Stephen Kelly a3d0ae1758 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.

Stephen Kelly 82c283f914 Features: Use the correct dialect flag when recording features.
Avoid using -std=c++1y for compilers which support -std=c++14, for
example.

Brad King 6e34aea93c Clang: Split Compiler/Clang* modules out from GNU (#13550)
While Clang presents an almost identical interface to GNU there will be
some differences.  Split the compiler information modules to allow
separate rules for Clang.  Start by loading the GNU rules but leave a
place to add Clang-specific information.

Brad King 571dc74891 Recognize Clang C and C++ compilers (see #10693)
Map to the platform and compiler information for GNU because the
compilers are command-line compatible for common operations.  Later we
can add Clang-specific features as necessary.  We honor the preferred
capitalization is "Clang", not the common mis-spelling "CLang".
