[ARM] Basic gather scatter cost model

[dmgreen]

Summary

This is a very basic MVE gather/scatter cost model, based roughly on the code that we will currently produce. It does not handle truncating scatters or extending loads correctly yet, as it is difficult to tell that they are going to be correctly extended/truncated from the limited information in the cost function.

This can be improved as we extend support for these in the future.

Based on code originally written by David Sherwood.

Looks very reasonable to me.

The gather/scatter pass can also handle a sext here, in the manner that it will just leave it the way it is and use the result if it's of the correct type. That increases VectorCost by the cost of the sext, but doesn't necessarily mean that building a gather is more expensive than expanding.

Ah, I moved some code around and it no longer made sense.

This is apparently how clang-format wants this. But I think this line was wrong anyway. I've re-done it using DL.

922–924

We will only get to this point if we are dealing with either an i16 or i8 gather, in which case we need the address to be zext to be folded into the instruction otherwise we need to expand.

For i32's, I think we can always produce something. So up above there's a check that if EltSize == 32, we return VectorCost.

It is true that the zext here will still show up as a cost where it shouldn't, the instruction will fold it in. That is something that we can fix later I think, maybe at the same time that we improve the sext/zext/trunc handling.
