slm_cost/intel_cost and TARGET_SLOW_PSHUFB are just preparation to a
next vectorization patch.
Changes in ix86_add_stmt_cost gives real performance to Silvermont.
Let's move all to stage1.

Hi,
The patch is for x86 Silvermont.
It improves x86 Silvermont vector cost model.
It gives +20% on facerec spec on Silvermont.
It passes make check and bootstrap on x86.
Is this patch ok for stage1?
