Proper error message in native codegen

[Simon Peyton-Jones]

I'm not sure that the native codegen has a decent error reporting mechanism, I'm afraid.  It probably should.  I wonder if CoreToStg might do this instead?

Hi Simon,

A simple question (I think): is the best way to bail out of the native codegen when hitting a vector op via calling sorry? Current error message:

ghc: sorry! (unimplemented feature or known bug)
  (GHC version 7.5 for x86_64-unknown-linux):
    The native code generator does not support vector
instructions. Please use -fllvm.

Thanks,
Geoff
