Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if
it comes back, it will be largely a rewrite, so keeping the old codebase in tree isn't helping anyone. llvm-svn: 116191

@ -970,9 +970,6 @@ clang currently contains some support for PPC and Sparc; however, significant
|

pieces of code generation are still missing, and they haven't undergone

significant testing.
|

|

<p>clang contains some support for the embedded PIC16 processor
|
||||
(FIXME: I haven't been keeping track of this; what should this say?).
|
||||
|

<p>clang contains limited support for the MSP430 embedded processor, but both
|
||||
the clang support and the LLVM backend support are highly experimental.
