MapperJITLinkMemoryManager uses a free list to keep track of available
memory regions. Using an IntervalMap instead of vector allow automatic
coalescing of memory regions as they are freed.

When memory is deallocated from MapperJITLinkMemoryManager deinitialize
actions are run through mapper and in case of InProcessMapper, memory
protections of the region are reset to read/write as they were previously

there is still space available.
