Hojun-Cho 8f0ce09f2a w6c: promote f32 arg to double in C-variadic tail (#14 )

C99 6.5.2.2p6 requires float->double promotion for floats in the
variadic region of a call; w6c emitted MOVSS (4B), so a C variadic's
va_arg(double) read 8B of garbage. Promote at push (CVTSS2SD) so the
8B slot holds a real double, covering the XMM-reg and >8-float spill
cases uniformly; fi/AL XMM-count is unchanged.

cstage only; the wwstage twin rides C2 (#10), which adds wwstage's
C-variadic-call codegen.
