Hojun-Cho aff7725f8f w6c: f32 arg-push/pop uses MOVSS not MOVSD (#143) ...

cstage spilled f32 args via MOVSD (8-byte); ABI-correct is MOVSS (4-byte,
single class) per SysV (ref/qbe amd64/emit.c:524 — slot-copy-through-XMM
follows the float class). wwstage already emitted MOVSS; align cstage up
via op_for(node_isf32) at the arg PUSH (cgen.c:5366) + POP (cgen.c:5469).
Byte-id-only divergence (callee reads the f32 param low-32 regardless),
but it blocked cs==ww — closes the f32-arg-push half of the float-register
family (#119/#122/#125/#157). Bootstrap-NEUTRAL (no f32-arg caller in the
990-997 gated path). Test 907_f32arg_run (f32-arg push single/multi/mixed/
stack, cs==ww byte-id). Make test 187/187 incl 990-997.

Unblocks fold-5b (strconv f32tos passes f32 to f32bits).
