i965/fs: Allow scalar source regions on SNB math instructions.
I haven't found any evidence that this isn't supported by the
hardware, in fact according to the SNB hardware spec:
"The supported regioning modes for math instructions are align16,
align1 with the following restrictions:
- Scalar source is supported.
[...]
- Source and destination offset must be the same, except the case of
scalar source."
