Revert r75581: it causes massive breakage in the Ada
...
testsuite, due to exception handling not working
correctly. Maybe because the libgcc unwinder is
miscompiled - not sure, and I won't have time to
look into it before leaving on holiday. Note that
miscompilations of libgcc are not picked up by the
nightly testers, because they dynamically link with
libgcc, so pick up the system version rather than
the version built as part of llvm-gcc. This is a
nasty flaw in the nightly testers. (On the other
hand the Ada testsuite links with the just built
libgcc).

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.

Add some support for iterative coalescers to calculate a joined live
...
range's weight properly. This is turned off right now in the sense that
you'll get an assert if you get into a situation that can only be caused
by an iterative coalescer. All other code paths operate exactly as
before so there is no functional change with this patch. The asserts
should be disabled if/when an iterative coalescer gets added to trunk.

Fix ocaml tests for 64-bit MacOS systems. LLVM is currently built

as 32-bit code by default, and if gcc defaults to 64-bit code then ocamlc

and throwing away any other compiler options that were determined when
ocamlc was configured and built.
