Brad King a603250a13 Load platform files that need to know the ABI when possible
Load platform files named in CMAKE_<lang>_ABI_FILES for each language
once the ABI sizeof(void*) is known.  During the first configuration
this is after the test for working compiler and ABI detection checks.
During later configurations the ABI information is immediately available
because it has been saved in CMake<lang>Compiler.cmake.
