Detailed Description

Manages a set of 'lazy call-through' trampolines.

These are compiler re-entry trampolines that are pre-bound to look up a given symbol in a given JITDylib, then jump to that address. Since compilation of symbols is triggered on first lookup, these call-through trampolines can be used to implement lazy compilation.

The easiest way to construct these call-throughs is using the lazyReexport function.
