[Mesa-dev] [PATCH v2 2/3] i965/fs: fix source type when emitting MOV_INDIRECT to read ICP handles

When generating the MOV INDIRECT instruction, the source type is ignored
and it is set to destination's type. However, this is going to change in a
later patch, so we need to explicitly set the proper source type.

brw_vec8_grf() creates an float type's fs_reg by default, when the
ICP handle is actually unsigned. This patch fixes these cases before
applying the aforementioned patch.
