vect: Convert cost hooks to classes
The current vector cost interface has a quite a bit of redundancy
built in. Each target that defines its own hooks has to replicate
the basic unsigned[3] management. Currently each target also
duplicates the cost adjustment for inner loops.
This patch instead defines a vector_costs class for holding
the scalar or vector cost and allows targets to subclass it.
There is then only one costing hook: to create a new costs
structure of the appropriate type. Everything else can be
virtual functions, with common concepts implemented in the
base class rather than in each target's derivation.
This might seem like excess C++-ification, but it shaves
~100 LOC. I've also got some follow-on changes that become
significantly easier with this patch. Maybe it could help
with things like weighting blocks based on frequency too.
This will clash with Andre's unrolling patches. His patches
have priority so this patch should queue behind them.
The x86 and rs6000 parts fully convert to a self-contained class.
The equivalent aarch64 changes are more complex, so this patch
just does the bare minimum. A later patch will rework the
aarch64 bits.
