It's mutable because we modify it inside `bundleOpenMP` if the vendor is 
`Intel`, where we call `containerizeOpenMPSPIRVImage` to put the device image 
into an ELF (which we can't do using clang because there's no SPIR-V linker). I 
agree it's not ideal to have to modify the image here, if you have a better 
spot to do that ELF packaging, let me know. Thanks
