[AMDGPU] WIP: Use implicit operands instead of RegScavenger for AGPR copy lowering on gfx908

[jrbyrnes]

Summary

By attaching implicit vgpr to these copies, they will be allocated and available at time of copy lowering, so we no longer need register scavenging. The price is that in high RP kernel, this may cause additional spilling.

This is a WIP while I investigate what is needed to do the same for AGPR copy "spills" (and potentially remove VGPRForAGPRCopy).

[jrbyrnes]

@arsenm, do you have any high level disagreements with the general approach here?

[jrbyrnes]

Per offline discussion -- we need to avoid adding new virt regs during live range splitting.

Tentative plan involves a two-part approach:

1. Rework RA prioritization s.t. AGPR live-range splitting (and copy emission) is reasonably rare on gfx908.
2. Attach as many implicit vgprs as reasonably possible (i.e. the PreRAOptimizations functionality here), and rely on VGPRForAGPRCopy in the rare copies in which no implicit operand is available.
