i386 + bcheck: fix __bound_local_new
...
With -b, this produces garbage. Code to call __bound_local_new
is put at wrong place, overwriting the regparam setup code.
Fix copied from x86_64-gen.c.
void __attribute__((regparm(3)))
fun(int unused)
{
char local[1];
}

tccgen: return: avoid jmp to retsym if possible
