// Mark functions as no-inline based on name wildcards. For example:
//
// --no-inline=*leave-alone* --inlining
//
// That will mark all functions with names like "runtime-leave-alone-1234" as
// no-inline, and as a result the inlining pass that happens afterwards will not
// inline them.
//
// Note that this is itself a pass, which does work - it marks things in the
// IR - and so the order of operations matters. If we did
//
// --inlining --no-inline=*leave-alone*
//
// then we'd first perform the inlining and then the marking, which would mean
// the marking has no effect.
