This won't actually do anything because the compiler still rounds the
size of the structure upto a multiple of sizeof(int) for alignment
purposes. With your v2 patch applied, I still get
(gdb) print sizeof(ir_state_slot)
$1 = 24
which is 6*sizeof(int).
I see, should've checked with 'pahole' tool first. As with
glsl_type::base_type, 'swizzle' here was something that I was hoping to
get smaller only from serialization perspective (shader cache work).
