i965/fs: Make emit_shader_time_write return rather than emit.

Instead of emit_shader_time_write, we now do emit(SHADER_TIME_ADD(...)).
The advantage is that we can also insert a shader time write at an
arbitrary location in the instruction stream, rather than being
restricted to emitting at the end.
