wcc: #99 alias-of-tuple — chase TY_NAMED in tuple coercion (cstage) + param spill (wwstage)

Browse Source 
type pair = (int, int); let x: pair = (3, 4) -- an alias of a tuple
initialized from an untyped literal, and passing such a value to a fn --
was a both-stage bug, mirror-twins of the same TY_NAMED-not-chased root:

cstage CHECKER over-rejected the init (not assignable to declared pair):
type.c's tuple-assignable arm gated on the un-chased dst kind, so a
TY_NAMED alias skipped the per-element untyped->int coercion the direct
tuple path applies. Fix: chase TY_NAMED both sides (mirrors the #258
slice-borrow arm). Direct and typed-alias tuples already worked; only
alias+untyped was rejected.

wwstage CGEN dropped the second word of an alias-tuple fn-arg: the
tuple-param spill at cgendecl.ww gated on the syntactic N_TTUPLE, so an
alias param (N_TNAME) fell to the scalar path and spilled one slot ->
t.1 read frame garbage. Fix: chase the alias via aliaslookup to the
resolved N_TTUPLE and spill all its slots. cstage cgen was already
correct -- the bug was checker-only there. Converges cs==ww byte-id.

One commit: same construct, the two halves must ship together (either
alone leaves cs!=ww). test/wcc/826 (init/fn-arg/return, 2-field byte-id);
test/wcc/944 4 rows graduated err->run-correct. byte-id 990-997 8/8.

/*
* 826_alias_tuple_coerce — an alias of a tuple type, initialised with an
* UNTYPED tuple literal, must coerce element-wise just like a direct tuple
* (task #99). `type pair = (int, int); let x: pair = (3, 4)` was rejected by
* cstage — `init (untyped_int, untyped_int) not assignable to declared pair`
* — while the direct `let x: (int,int) = (3,4)` and the typed-alias
* `let x: pair = (3:int, 4:int)` both compiled. wwstage already accepted+ran
* the untyped-alias form correctly.
*
* ROOT (cstage only): cmd/wcc/type.c type_assignable's tuple-to-tuple arm
* gated on the UN-chased `dst->kind == TY_TUPLE`. For `pair` (a TY_NAMED
* alias) dst->kind is TY_NAMED, so the arm was skipped and the per-element
* untyped->int coercion never ran. The fix chases TY_NAMED on both sides
* before the tuple check (mirroring the #258 slice-borrow arm just below),
* so an alias-of-tuple gets the same element-wise coercion as a direct tuple.
* type_assignable is the shared assignability predicate, so INIT, FN-ARG and
* RETURN positions all flip reject->accept in one spot. cstage-only —
* wwstage check.ww/cgen are unchanged.
*
* The coercion still type-checks per element, so a genuinely mismatched
* element type or wrong arity STILL louds — those are the negative controls.
*
* row | shape | want
* ------------+------------------------------------------------+------
* init | type pair=(int,int); let x:pair=(3,4); x.0+x.1 | 7
* fnarg | fn g(p:pair); g((3,4)); p.0+p.1 | 7
* ret | fn f() pair = { return (3,4); }; r.0+r.1 | 7
* mixed | type box=(int,u16); let x:box=(3,4); coerce ea | 7
* ctrl_dir | direct (int,int)=(3,4) (no-regress) | 7
* ctrl_typed | alias (3:int,4:int) (no-regress) | 7
*
* init / fnarg / ret / mixed are the mutation-sane rows: pre-fix cstage
* build-FAILS them (the untyped->alias coercion was rejected); pre-fix
* wwstage built but a two-field alias-tuple fn-arg read garbage (the param
* spill half). Post-fix BOTH stages build+run the want.
*
* Negative controls (cstage must STILL loud — don't over-accept):
* neg_type | let x:pair=(3,"s") (element type mismatch)
* neg_arity | let x:pair=(3,4,5) (wrong arity)
*
* byte-id: the init, fnarg and ret rows are asserted byte-identical
* (cstage==wwstage .s). #99 shipped in two halves — the cstage type.c chase
* (init/fnarg/ret reject->accept) AND the wwstage cgendecl.ww tuple-PARAM
* spill chase (the param twin: an alias param gated on the SYNTACTIC
* N_TTUPLE node fell through to the scalar path, spilling one arg reg and
* dropping the second tuple word, so a two-field read of an alias-tuple
* fn-arg returned garbage in wwstage). With the wwstage half landed the
* fnarg/ret prologues converge to cstage, so both read both fields and
* match byte-for-byte. mixed (an init row) stays runtime-only.
