test: migrate Fam11 float value tests to @test, keep ABI-conformance pins (#5-C4)

Browse Source 
fold-2 chunk C4 (drew's Fam8-13 plan): 13 float value-row C drivers re-homed.
11 migrate to test/lang/*_test.ww @test row-tables (exact IEEE-bit asserts);
1 float-overflow reject row -> a runww //ww:error carrier. 956_tuprecv_f64
slims to a w6c_ww asserttyped pin (20 value rows -> @test; the stamp dimension
can't be a value/byte-id @test) -- mutation-proven non-vacuous (break #121
stamp -> RED 6/6 -> restore -> GREEN) + an in-test vacuity self-check.
946_structparam/structret stay whole: their SSE register-class .s-grep (SysV
ABI conformance, #165/#171a) is the genuine defect-guard, not @test-expressible.
Float was the predicted SSE-cursor byte-id hotspot -- zero fresh cs!=ww
surfaced; 951_f64cgen (cstage-only before) byte-ids clean. LANGBYTEID floor
82->93; test count 384->374 (10 deleted drivers; 956 + the 2 946 kept).

/*
* 956_tuprecv_f64_run — runtime + byte-id regression net for #105 and
* the #164 (#107) multi-float extension.
* 956_tuprecv_f64_run (SLIM PIN, #5-C4) — the #121 A-narrow asserttyped stamp
* dimension for the f64 tuple-receive DESTRUCTURE bindings. The runtime VALUE
* rows + cs==ww byte-id migrated to test/lang/tuprecv_f64_test.ww; what stays
* here is the one dimension test-lang has no channel for: a wwstage-STDERR grep
* that w6c_ww emits NO `asserttyped:` diagnostic on the un-annotated float
* destructure binding (the binding must carry a checker type stamp so cgen's
* class-aware spill fires). cstage has no ww asserttyped pass, so this is
* w6c_ww-only by construction (project memory: audit the *_ww binary).
*
* #164 (#107): a multi-float tuple return (e.g. (f64,f64)) mis-routes —
* the SEND emitted every float through X0 (cgexpr clobbers X0 per
* element), so two floats collided on X0 and the receive read both from
* X0. The fix gives the tuple return a SysV SSE cursor [X0,X1] parallel
* to the integer cursor [AX,DX,CX,R8]: a float rides the next XMM on an
* INDEPENDENT counter (ref/qbe/amd64/sysv.c retr). The SEND spills each
* float to @tupfscr as it walks (X0 is clobbered by later elements) and
* reloads X0/X1 by SSE index after the integer pops; every receive site
* (single-var 16B/32B, destructure, reassign) reads the float from its
* SSE-cursor reg. SSE caps at 2 (X0,X1) — (f64,f64,f64) is over-cap, so
* it returns via sret (#10 Fold A SEND + Fold B destructure RECEIVE); the
* f64x3_recv row asserts that round-trip works in both stages.
* NON-VACUITY (drew C4 mutation gate): the grep is LIVE — pre-stamp HEAD w6c_ww
* fires `asserttyped` on the f64 binding ident (nil n.type_), and the grep
* mechanically fires on a synthetic `asserttyped:` line (self-checked below at
* startup; a broken grep FAILS the test before any row runs).
*
* #105 (original): a tuple-from-call receive corrupts the f64 word when
* the callee is BRANCHED. Covers ALL THREE receive forms, which share the
* #83 tuple_rseq cursor and all carried the same defect:
* 1. SINGLE-VAR `let r = norm(); ...r.0` (cglet 16B-tuple branch)
* 2. DESTRUCTURE `let (m,i) = norm()` (N_MLET / cgmlet+tupstore)
* 3. REASSIGN `m,i = norm()` (N_MASSIGN / cgmassign+tupstore)
*
* Root (#105, a #103-FACE-Z regression): a (f64,i64)/(i64,f64) tuple
* returns its f64 word in X0 (the SSE return reg) and its integer word
* in an integer reg (tuple_rseq AX/DX). All three receives spilled the
* f64 word via MOVQ from the integer cursor — but that reg holds GARBAGE
* (the f64 is in X0). #103-FACE-Z's field read (MOVSD slot,X0) then read
* that garbage. The fix makes every receive spill CLASS-AWARE: an f64/f32
* word spills `MOVSD/MOVSS X0, slot`, an integer word spills `MOVQ
* <reg>, slot` (as before). cstage cgen.c (3 sites) + wwstage cgenstmt.ww
* (cglet branch + the shared tupstore helper, which covers cgmlet and
* cgmassign), identically.
*
* WHY BRANCHED CALLEES: a SINGLE-return callee masks the bug via
* register coincidence — a float-literal return leaves the f64 bit
* pattern in AX (literal materialise goes through AX), so MOVQ AX,slot
* happens to store the right bits; and X0 stays live to the receive. A
* BRANCHED / multi-statement callee whose f64 word is a non-literal
* (e.g. an f64 param) has an inner CALL clobber AX, so the integer-reg
* spill stores garbage. The bug rows below therefore all use branched
* callees with an f64-param word — single-return rows are gate-blind to
* #105 (this is the gate lesson the task pins).
*
* GATE-BLIND TO BYTE-ID ALONE: both stages are symmetric-WRONG on master
* (both emit MOVQ AX,slot), so the cs==ww .s gate HOLDS on master for
* the bug rows — they diverge only at RUNTIME. Each row carries BOTH
* dimensions (modelled on 954_tuprecv_run):
* (a) cstage `ww build` + run, asserting the exit code — this is what
* catches #105 (master returns the wrong exit).
* (b) w6c vs w6c_ww `.s` cmp — guards rule-10 (both stages fixed
* identically).
*
* CONTROL rows pin that the fix touches nothing else: an all-integer
* branched 2-tuple (correct pre- and post-fix; MOVQ path untouched), the
* destructure form `let (a,b)=mk()` (cgmlet, a separate path the fix
* does not touch), a single-return (f64,i64) field read (#103 FACE-Z
* shape, correct pre- and post-fix), and a bare 0f64 compare (#103
* FACE-X shape, no tuple involved).
* Slim sibling of the C2 precedent (954 ctl_destr's asserttyped sub-dimension,
* test/lang/tuprecv_test.ww). The 6 rows are the chk_stamped subset of the
* original 956 driver; non-float / control rows carry no stamp dimension and
* live only in the @test file.
