This is a backport of a change Loren made to sync FSF GCC with some local 
changes FreeBSD has done and, sadly, not fed back upstream.  Without this
change, GCC 4.4 regresses versus the GCC 4.2-based system compiler.

Tested on i386-unknown-freebsd9.0.  The number of unsupported "gcc"
tests decreased by 4, the number of expected passes increased by 10.

Installed based on prior approval by Loren.
