GlobalValue is destroyed. Function destruction still leaks machine code and
can crash on leaked stubs, but this is some progress.

mappings, which could cause errors and assert-failures. This patch fixes that,
adds a test, and refactors the global-mapping-removal code into a single place.

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.

This involves temporarily hard wiring some parts to use the global context. This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

default, this option is not enabled to support clients who rely on
this behavior.

A patch to allocate additional memory for globals after we run out is
forthcoming.

emitted or the machine code for a function is freed. Chris mentioned that we
may also want a notification when a stub is emitted, but that'll be a future
change. I intend to use this to tell oprofile where functions are emitted and
what lines correspond to what addresses.
