81ce3ed08c Make the JIT code emitter properly retry and ask for more memory when it runs 
out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

95eb3ad353 Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using 
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

6dae757a07 Don't give a massive inlining cost bonus to available_externally 
functions with a single use; eliminating the single use may eliminate 
the function from the current module, but usually doesn't eliminate 
it from the final program.
