Do not bother enabling C++ in Assembler test This test needs only the C compiler and ASM compiler so do not enable the C++ compiler.

Teach Assembler test to generate main.s at build time Use a custom command to generate the assembly source file at build time. Also set CMAKE_VERBOSE_MAKEFILE so the test output contains all the build rules. These two changes will show the entire .c -> .s -> .o and final link commands in the test output.

Tests/Assembler: Do not use assembler in universal binaries If CMAKE_OSX_ARCHITECTURES is set then the computed assembler .s source file may not work for all architectures. Skip it in that case.

Clang: Add separate "AppleClang" compiler id Apple distributes their own Clang build with their own version numbers that differ from upstream Clang. Use the __apple_build_version__ symbol to identify the Apple Clang compiler and report the Apple Build Version as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION. Add Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules that simply include the upstream equivalents. Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own source and tests to account for AppleClang.

Fix Assembler test to parse C flags string before using Commit 1f6c6b1c (use CMAKE_C_FLAGS when generating the assembler file, 2011-03-03) added use of CMAKE_C_FLAGS to the assembler generation step. However, this variable is meant for direct substitution into a shell command line so we need to parse it to separate the arguments first.

Tests/Assembler: Use CMAKE_OSX_SYSROOT to generate .s file On OS X if the user-provided flags do not include -isysroot and CMAKE_OSX_SYSROOT is defined then add the proper -isysroot flag to the C compiler invocation we use to generate the .s file.

Tests/Assembler: Drop -g when generating sample assembly source Some compilers, such as Clang on OS X, do not want the -g flag for both generating assembly code and assembling it. Drop the -g flag from generation of main.s in the Assembler test.
