Subject: Mark these as failing on sparc instead of sparcv9. The configure
 script no longer tells us that we're configuring for SparcV9 specifically.
 2004-06-17-UnorderedCompares may work on SparcV8, but it's experiental
 anyway. 2005-02-20-AggregateSAVEEXPR should fail on any Solaris machine, as
 Solaris doesn't provide complex number support.
