Aarch64: Change costs for TX2 to expose more vectorization opportunities

Make the costs such that they do not exaclty reflect
the actual instructions costs from the manual but make
the codegen emit the code we want it to.

* config/aarch64/aarch64.c (thunderx2t99_regmove_cost,
thunderx2t99_vector_cost): Likewise.
