10b4fc552f Re-committing r76828 with the JIT memory manager changes now that the build
bots like the BumpPtrAllocator changes.

4bf370698a Reverting r76825 and r76828, since they caused clang runtime errors and some build failure involving memset.

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.

932a32d251 Update the stub and callback code to handle lazy compilation. The stub
is re-written by the callback to branch directly to the compiled code
in future invocations.

Added back in range-based memory permission functions for the updating of
the stub on Darwin.

0554575567 For PR797:
Make the Win32 code exception free (untested/uncompiled) which forced some
interface changes which had ripple effect. This should be the last of 797.
