"fix" PR4612, which is a crash on:

%0 = malloc [3758096384 x i32]
The "malloc" instruction doesn't support 64-bits correctly (see PR715),
and should be removed. Victor is actively working on fixing this, in
the meantime just don't crash.

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.

functions with a single use; eliminating the single use may eliminate
the function from the current module, but usually doesn't eliminate

Let each target determines whether a machine instruction is dead. If true, that allows late codeine passes to delete it.

This is considered a workaround. The problem is some targets are not modeling side effects correctly. PPC is apparently one of those. This patch allows ppc llvm-gcc to bootstrap on Darwin. Once we find out which instruction definitions are wrong, we can remove the PPCInstrInfo workaround.

should be disabled if/when an iterative coalescer gets added to trunk.

whitespace cleanups, make the MipsAsmPrinter::doInitialization

This gives it .file and module level inline asm support among other
