Hi Uros,
This patch is to update mtune for tremont.
Bootstrap is ok, and no regressions for i386/x86-64 testsuite.
OK for master?
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.

* config/i386/i386.c (ix86_vector_costs::add_stmt_cost): Remove Tremont.
