Some compilers try to simulate other compilers as a drop-in replacement supporting all the same command-line options and predefined preprocessor macros. In such cases it will be useful to have CMake load the compiler information files for the simulated compiler instead of duplicating the information. Teach CMakeDetermineCompilerId to extract the simulated compiler id and version when the compiler id detection provides it.
