Subject: Add support for Assembler with C Preprocessor (.S) compilation

Specifically, the c module now provides the c.as-cpp submodules which can be
loaded in order to register the S{} target type and enable Assembler with C
Preprocessor compilation in the c compile rule. For details, refer to
"Assembler with C Preprocessor Compilation" in the manual.
