Thanks for adding all the `// SAFETY` comments here Boqun!

Björn, do they look good to you? (since you fixed the issue in the compiler)

On this comment in particular, "generated at `GlobalAlloc` callsites"
sounds a bit confusing to me. Would "... called by the compiler with
parameters that obey ..." make sense? Or does the sentence refer to
the normal case (i.e. when the functions are generated)? Anyway, it is
not a big deal.

Cheers,
Miguel
