Summary:                    enable_language() sets CMAKE_<lang>_COMPILER_LOADED
in local scope
Description: 
When enable_language(<lang>) is called within a function, it sets the variable
CMAKE_<lang>_COMPILER_LOADED within the scope of that function only. This
behaviour is rather unexpected, or at least not mentioned in the documentation.

Steps to Reproduce: 
Run CMake on the attached CMakeList.

Expected output:
-- C was loaded
-- C reports as loaded

Actual output:
-- C was loaded
-- C reports as not loaded
