Keep Julia values and runtime globals as symbolic host references until final backend lowering, instead of persisting session addresses in IR or cached metadata.
Normalize runtime globals into word-sized slots, sanitize value-global names, and make reference-aware linking collision-safe. Default backends still embed current-session values; loaders may retain relocatable slots.
For example in CUDA.jl, JuliaGPU/CUDA.jl#3200, we can use CuGlobals to populate the IR at load time, making it possible to cache even generated PTX code. Other back-ends fall back to relocating at compile time; the default behavior of GPUCompiler.jl.
Supersedes #125 and #348
