Sorry for the delay. Attached is a new version of this patch.

In this patch the scalar and vector version of ceq_v2df_celledp and 
cgt_v2df_celled are combined using mode macros. 
A test case intrinsics-2.c is added to test spu intrinsic functions on 
cell. 
Two test cases dfcmeq.c and dfcmgt.c are used to test generation of dfcmeq 
and dfcmgt instructions combined from double precision compare and 
absolute operations.
In addition, vcond patterns are added to support vector conditional 
expression. Test case fast-math-vect-reduc-7.c is switched on to test 
vcond pattern.



Thanks!
