PATH: sparc64 bootstrap problems on FreeBSD (PR 10453)

[Alexander Kabaev]

The patch below fixes a bug in GCC which renders compiler unusable on
FreeBSD. The patch was reviewed by  Jakub Jelinek <jakub@redhat.com>
already and was found to be ok.

I successfully bootstraped GCC mainline and GCC 3.3 on FreeBSD
5.0-CURRENT and on Solaris8. The test suite run with no regressions on
Solaris with this patch applied.

I am asking permission for this patch to be applied to both trunk and
gcc-3_3-branch. Since I do not have write access to GCC repository,
Loren James Rittle <rittle@labs.mot.com> has agreed to apply the patch
if it is approved.

	* config/sparc/sparc.md (umulsidi3, mulsidi3): Avoid using
	const_umulsidi3_sp32 and const_mulsidi3_sp32 on 64bit targets 
	where they might be not present. Use their _sp64 equivalent
	instead.
