-- Per-macro cycle cost (best-case, no stalls). Used by the static-analysis
-- `count_atom_cycles` pass (Phase 3) to emit per-atom cycle budgets. The
-- counts cover the EXPANDED instruction sequence the macro emits (NOT just
-- the token it appears as in source). For example:
--
-- mac_pack_color_word(off, cmd, r, g, b) emits:
-- load_upper_i(R_AT, (cmd << 8) | b) -- 1 cycle
-- or_i_self(R_AT, (g << 8) | r) -- 1 cycle
-- store_word(R_AT, R_PrimCursor, off) -- 1 cycle
-- = 3 cycles total
--
-- mac_yield emits a control-transfer sequence (load_word, add_ui_self,
-- jump_reg, nop) which "yields control" -- the atom body's cycle budget
-- doesn't include the yield's cost (we model it as 0; runtime cost
-- becomes part of the NEXT atom's prologue).
--
-- GTE command values are the GTE instruction's intrinsic cycles (the
-- latency AFTER any pre-cmd `nop2` has retired). When the source emits
-- `nop2, gte_cmdw_X` the nops' cycles are added separately (1+1) plus
-- the gte_cmdw_X value here:
-- rtpt = 21 + 2 nops = 23 total cycles (matches PSX-SPX)
-- rtps = 12 + 2 nops = 14 total
-- nclip = 6 + 2 nops = 8 total
-- avsz3 = 12 + 2 nops = 14 total
-- avsz4 = 14 + 2 nops = 16 total
-- mvmva = 6 + 2 nops = 8 total
-- op = 5 (no pre-cmd nops required; single-cycle atomic)
