Reid Kleckner 1a722d9b73 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.

Daniel Dunbar 38e46c46b4 Unbreak unittests build.
- Reid, please check, I'm not sure if this is what was intended.

Owen Anderson 53a52215b5 Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp.
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.

Jeffrey Yasskin 70415d97a8 Add an option to allocate JITed global data separately from code. By
default, this option is not enabled to support clients who rely on
this behavior.

Fixes http://llvm.org/PR4483

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

Patch by Reid Kleckner!

Jeffrey Yasskin 0b08f3d7cc Add a JITEventListener interface that gets called back when a new function is
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.
