i386.md (truncdfsf2_*): Add i387->int/sse reg alternatives... 

* i386.md (truncdfsf2_*): Add i387->int/sse reg alternatives;
	Do not require source to match destination anymore;
	Add abort to the nontrivial cases that should be handled by split.
	(fix_trunc?fdi): Add SSE case for x86_64.
	(floatdi?f): Likewise.
	(floatdi?f_sse): New.
	(fix_trunc?fdi_sse): New.
