[LLVMdev] PIC Micropchip Backend

[Anton Korobeynikov]

PIC backend was removed because it was written violating almost every
LLVM programmer's guidelines and, even more, the authors refused to
address review comments.

So, it started to bitrot quite fast, noone from the community felt
brave enough to maintain it and thus it was removed.

Therefore it's stongly adviced not to use old PIC backend for any
revival nor new development. Please consider developing new one from
scratch "in proper way" :)
