[PATCH, i386]: Committed: Fix gcc.target/i386/sse-13.c failure

[Uros Bizjak]

Hello!

We should not calculate "memory" attribute for 1st alternative of  
*vec_extractv2di_1_sse2. This  alternative is marked as "sseishft" type, 
and "memory" calculation for this type expects operands[2]. The solution 
is to force "memory" attribute to "none" for this alternative.

(BTW: This error was found due to sse-13.c test, which was recently 
changed to cover and test all sse/mmx intrinsics.  Way to go. :) )

Patch was bootstrapped on x86_64 and regression tested with -m32 that 
triggers this heisenbug. Patch was commited to SVN.

        * config/i386/sse.md (*vec_extractv2di_1_sse2): Do not calculate
        "memory" attribute for "sseishft" type insn without operands[2].

Uros.
