b500f07edf 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.

4c892c05ec Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using 
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

2a4535353f Revert commit 76707, it was breaking the llvm-gcc build 
on linux platforms.  The binutils assembler does not
recognize the "s" flag, see for example

ca2e01b721 Don't give a massive inlining cost bonus to available_externally 
functions with a single use; eliminating the single use may eliminate 
the function from the current module, but usually doesn't eliminate 
it from the final program.

e2bd5bc939 remove the SelectSectionForMachineConst hook, replacing it with 
a new getSectionForMergableConstant hook.  This removes one dependence
of TAI on Type, and provides the hook with enough info to make the 
right decision based on whether the global has relocations etc.

82499c09ff 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.

48dffde0d7 reimplement Constant::ContainsRelocations as 
Constant::getRelocationInfo(), which has a much simpler
to use API.  It still should not be part of libvmcore, but
is better than it was.  Also teach it to be smart about 
hidden visibility.
