cstage cmd/wcc/check.c:702 cexpr N_FLOATLIT arm uses lookup_builtin
(n->tsuffix) with fall-through to ty_untyped_float. wwstage's
exprtype N_FLOATLIT arm at check.ww L1582 was unconditional
untyped_float — the symmetric-stage gap flagged at the tail of #51.
New arm: when e.tsuffix is non-empty, mktname+tinfofornode resolves
the builtin and stamps e.type_; on nil tinfo fall through to the
existing untyped_float path. Same shape as the #51 INTLIT arm one
block up.
Byte-identity (994/995) is the behavior gate; full make test green
at 133/133 confirms.
