Just discovered that the library LLVMpic16passes is odd on several
accounts:
* It doesn't follow the naming schema of the rest of the libraries for
that target (should be LLVMPIC16Passes)
* Nothing references it.
* It differs from the typical library layout of an LLVM target (no
other target has a LLVM*passes library)
I've changed the name to LLVMPIC16Passes (originally it was PIC16Passes
but seems that it was accidentally changed to LLVMpic16passes instead of
LLVMPIC16Passes.)
