Bob Wilson a0be09f511 Add LLVMContext::emitWarning methods and use them. <rdar://problem/12867368> ...

When the backend is used from clang, it should produce proper diagnostics
instead of just printing messages to errs(). Other clients may also want to
register their own error handlers with the LLVMContext, and the same handler
should work for warnings in the same way as the existing emitError methods.
