Embarcadero: Check code using CMAKE_CXX_COMPILER_ID and CMAKE_C_COMPILER_ID.

The CMAKE_CXX_COMPILER_ID and CMAKE_C_COMPILER_ID variables are set to
"Borland" for older versions of the compiler.  Newer CodeGear/Embarcadero
compilers will have those variables set to "Embarcadero".  Search for lines of
code referencing both the variable name and Borland to be sure that they also
refer to Embarcadero.
