More dtable fixes - now the EtoileFoundation tests work when compiled with GCC too. Hopefully that's all of the irritating corner cases in category loading dealt with...

More fixes for the new dtable. Now passing all of the EtoileFoundation tests, which do lots of things involving categories, so make a good stress test.
...
No longer installs headers by default. This is because GNUstep Make notices when the objc headers have changed (because GNUstep includes them) and so reinstalling libobjc2 was requiring a complete recompile of anything that you tried to build, even if you only changed one line. A better fix for this would be for install to use cmp or diff to check if the header has been modified before installing it, but I'm too lazy to do that right now.

Fixed the definition of objc_msgSendSuper().
Tweaked the -dealloc implementation for hidden classes used for locking so that @synchronize(self) will work in a -dealloc method.

Return NULL instead of "" from sel_getTypes_np() - matches behaviour of sel_get_types() and makes more sense.

Add empty sarray.h - for some reason GNUstep is trying to #include this file (no idea why, as nothing in GNUstep actually uses anything from it). Adding an empty version should prevent breakage for now.

Fixed some issues in runtime.c when looking up methods. This fixes some issues with DO.
...
Removed GNU dtable and sparse array implementations, replaced entirely now with versions based on the Étoilé runtime. Performance is roughly equivalent in microbenchmarks, memory usage is significantly lower (Gorm goes from 95MB to 50MB on my machine - this will be even more pronounced on 64-bit systems), which should improve cache usage considerably. Still room for some performance tuning, however.

Unrolled the SparseArrayLookup loop. This means we only need one jump, instead of 2, which gives the same performance as the old GNU code and about half the memory usage. It's really, really, ugly code though - I need to teach the compiler to do this optimisation so I don't have to.

Some bug fixes and tidies.
...
I now have an out-of-tree replacement for the dtable stuff, so sarray.{h,c} will be going away soon. The replacement offers similar (slightly worse currently) performance in microbenchmarks, but uses half as much memory (Gorm goes from 95MB to 48MB on my machine). This will be committed once it's been tweaked a little bit.

Factored out dtable stuff into dtable_legacy.c so that it can be replaced and so that we can do some profiling of the replacement to make sure it doesn't introduce performance regressions.

Tidied up some bits by creating private headers for private data structures.

Imported selector table code frm the Étoilé runtime. We can now make dispatch type dependent with a -D switch. Not enabled yet, but it will be enabled in a warning mode soon - I consider preferable to the existing GNU and Apple solution of corrupting the stack.

Commented out some premature termination code. This is a bit of a hack; we're now repeatedly adding the same methods to dtables, which is ugly. We ought instead to be able to test if something is a lazy copy.

Initial (working) type feedback pass. Records the IMP for every message lookup. Note: This writes 3 words for every single message send, which means that it makes code VERY slow and can fill up the filesystem if you leave it enabled.
...
The aim of this pass is to identify message send sites which can benefit from speculative inlining and inline caching. By itself, this pass is useless. It will later be combined with one that parses this information and then uses the existing caching and inlining infrastructure to optimize hot message send sites.
Now, however, it's time for me to go and dance, so the useful bit will have to wait.

Simplified profiling system and enabled it by default. This should be safe, because it no longer depends on dladdr() and friends (which don't work reliably anywhere), and instead expects the profiling modules to register their own symbol table.

Aside: Testing the two passes from the last commit shows that they provide about a factor of 10 speedup for class messages.

Added -gnu-class-lookup-cache and -gnu-class-imp-cache passes. These add caching for class messages and also skip the class lookup (using the class symbol directly) where possible.
...
In combination, these make class messages marginally slower than function calls, rather than significantly slower than message sends.

Fixed IMP cacher to not cache the slot if the lookup function changes the receiver (this could result in a method being called on the wrong receiver, which would just be confusing).

Factored out code that performs IMP caching into a separate class. This can now be used by other passes that cache IMPs outside of loops (for example, always caching class messages because they always have the same receiver).

Microbenchmark that just sends a message that does nothing 1000000000 times in a loop goes from taking 10.2 seconds to taking 4.7 after running the pass.
