Subject: Detect calls to compiler intrinsics and emit an extern declarations
 only for those. These extern declarations to intrinsics are currently being
 emitted at the bottom of generated .s file, which works fine with gpasm(not
 sure about MPSAM though). PIC16 linker generates errors for few cases
 (function-args/struct_args_5) if you do not include any extern declarations
 (even if no intrinsics are being used), but that needs to be fixed in the
 linker itself.
