util/tgsi: use ASSERT_BITFIELD_SIZE() to check opcode field size

Browse source 
I've noticed at least two places where we store the TGSI opcode in
an unsigned:8 bitfield.  We're at 249 opcodes now.  If we hit 256 we'll
need to grow those bitfields.  Use the new ASSERT_BITFIELD_SIZE() macro
to detect that.
