Unsuccessful attempt to avoid stack realignment for DImode and for DFmode at
-Os

Just for the record, here is an unsuccessful attempt to avoid stack realignment
just because of DImode for -m32 or because of DFmode at -m32 -Os.  This patch
unfortunately caused a handful regressions, like 20020220-1.c.
