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).

change a test to run in filecheck style.  Rename it to be a general
dumping ground of various SSE4.1 tests, since filecheck can reasonably
handle them all in one file.  Generalize it to check x86-64 stuff as
well since it has a different ABI (a convenient way to test both the
reg and mem forms of these instructions).

Reverting r76825 and r76828, since they caused clang runtime errors and some build failure involving memset.

Fix error message for correct opcode.

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.

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.

remove SectionFlags::Small: it is only used on Xcore, and we'll find
