rlx-compile

HIR → MIR → LIR compile pipeline for RLX: CompilePipeline, backend legalization, memory planning, precision / PTQ passes.

Depends on rlx-ir and rlx-fusion.

What's here

compiler — CompilePipeline, CompileResult, pipeline inspect hooks.
fusion_pipeline — fusion_passes, fusion_passes_for_supported, backend-aware pass lists.
legalize / legalize_broadcast — rewrite graphs for a target device.
memory — liveness analysis and arena slot assignment.
precision — auto-mixed precision policy (f32 ↔ f16/bf16 around matmul).
quant_insert / quant_propagate — PTQ Q/DQ insertion and propagation.
const_fold, dce, inline, promote_params, svg.
param_specialize — bake fixed Op::Param tensors into Op::Constant before DCE / constant folding (CompileOptions::param_bindings in runtime).
algebraic_simplify — same-shape x*0, x*1, x+0 rewrites (safe only when constant rank matches output; no scalar-broadcast folding).

Kernel dispatch transparency

prepare_graph_for_backend_with_report and friends produce a KernelDispatchReport (native vs common-IR vs rewritten vs unsupported). The runtime uses the same legalization path as compile; see the root README.md for env vars (RLX_DISPATCH_REPORT, RLX_KERNEL_DISPATCH).
