Factor common code out of CMakeDetermine(ASM|C|CXX|Fortran)Compiler
The compiler candidate list selection and search code for C, C++, ASM, and Fortran languages was duplicated across four modules. To look for compilers adjacent to already-enabled languages the C and CXX modules each used _CMAKE_USER_(C|CXX)_COMPILER_PATH and the ASM module used _CMAKE_TOOLCHAIN_LOCATION. Since commit 4debb7ac (Bias Fortran compiler search with C/C++ compilers, 2009-09-09) CMake prefers Fortran compilers matching the vendor and directory of an enabled C or C++ compiler. Factor out the common functionality among the four languages into a new CMakeDetermineCompiler module. Generalize the Fortran implementation so that all languages may each use the vendor and directory of the other languages that have already been enabled. For now do not list any vendor-specific names for C, C++, or ASM so that only the directory preference is used for these languages (existing behavior).
