x86: Update -mtune=tremont
Silvermont has a special handle in add_stmt_cost function, because it has in
order SIMD pipeline. But for Tremont, its SIMD pipeline is out of order,
remove Tremont from this special handle.
gcc/ChangeLog
* config/i386/i386.c (ix86_vector_costs::add_stmt_cost): Remove Tremont.
