Pre-compilation broken on Julia versions < 1.10.11

Start with the reported failing precompilation on Julia 1.10.10 and inspect the stack trace entry in GPUCompiler.jl's relocation.jl at collect_julia_value_relocations!, then review the linked GPUCompiler.jl utils.jl comment. Compare behavior across Julia 1.10 versions before and at 1.10.11. Done means GPUCompiler precompiles on supported Julia 1.10 versions, with a regression check for the reported failure.

The project.toml allows any version of Julia 1.10 to be used, but after GPUCompiler.jl v2.11.0, precompilation errors on any Julia v1.10 version before v1.10.11. I believe this issue is caused by some interaction with LLVM.jl v10. Maybe this comment is relevant, because the jl_get_llvm_gvs_globals it refers to only exists in v1.10.11.

Apologies if this is not an actual issue or if the issue belongs in another repo.
