Alternative to --check-bounds=no?

[johnomotani]

@sloede I've seen that you commented on a few Discourse threads and issues about the problems with --check-bounds=no (and helped me out once or twice - thanks!). I started another discussion thread recently, which got an interesting suggestion (https://discourse.julialang.org/t/removing-bounds-checking-for-hpc-check-bounds-unsafe/124897/17) to make a custom array package to disable just the bounds checks on array accesses. I started work on one, with some promising initial results for my code (https://discourse.julialang.org/t/removing-bounds-checking-for-hpc-check-bounds-unsafe/124897/20), but (unless there's a better design that I haven't thought of) it needs wrappers to access the optimised, Array-specialised implementations of various packages (LinearAlgebra, SparseArrays, etc.) so other contributors who want to support more things would be welcome! It's still experimental though, and I haven't yet decided whether to use it for my code, although I'm leaning towards making the jump. The package is InboundsArrays.jl:

If anyone here has thoughts, they'd be very welcome!
