Extends the
GPUVectorAllocpass to promote operands to LDS using asynchronous DMA operations (e.g., AMD GPU direct-to-LDS).Based on propagation of the
use_global_load_dmapropagation type during analysis, the pass inserts LDS allocation andasync_dmaoperations, if the necessary requirements are met. Otherwise, promotion falls back to load/store via registers.The inserted
async_dmaoperations are lowered and distributed by the pass landed in #24299 further down in the pipeline.This is part of #23782.
