[LLVMdev] llvmc for PIC16

This should work:

$ cd $LLVM_DIR/tools/llvmc/examples/mcc16
$ make

If you're building from some other dir, you'll need to update
mcc16/Makefile, so it knows where Makefile.common is located.

Yes, I know, the documentation doesn't talk about creating standalone
drivers. Sorry for that, I was planning to update it for ages...
For now, please look at examples/Skeleton, which is a standalone
driver skeleton, on which the mcc16 driver is based.

This section is about building the "main" llvmc driver and its plugins.
Creation of standalone drivers is not described in the docs yet (it
was added relatively recently).
