[Mesa-dev] [PATCH 4/6] i965/fs: do not require force_writemask_all with exec_size 4

[Samuel Iglesias Gonsálvez]

So far we only used instructions with this size in situations where we
did not operate per-channel and we wanted to ignore the execution mask,
but gen7 fp64 will need to emit code with a width of 4 that needs
normal execution masking.
