that have internal state when processing diagnostics.

a nice shiny B+ Tree variant.  This fixes the last of the known algorithmic
issues with the rewriter, allowing a significant speedup.  For example,
-emit-html on Ted's 500K .i file speeds up from 26.8s -> 0.64s in a 
debug build (41x!) and 5.475s -> 0.132s (41x!) in an optimized build.

This code is functional but needs to be cleaned up, ifdefs removed, better
commented, and moved to a .cpp file.  I plan to do this tomorrow.

much simpler than in LegalizeDAG because calls are
not yet expanded into call sequences: that happens
after type legalization has finished.

inheritance in C++. It'll parse the base-specifier list, e.g.,

 class D : public B1, virtual public B2 { };

and do some of the simpler semantic checks (B1 and B2 are classes;
they aren't unions or incomplete types, etc).

allows the parsing of "class" in addition to "struct" and "union" to
declare a record.  So this patch allows:

 class C { };
 class C c1;

But it does not contain the lookup bits, so this won't work yet:

 C c2;

in its maps.  Add some sanity checks that catch
this kind of thing.  Hopefully these can be
removed one day (once all problems are fixed!)
but for the moment it seems wise to have them in.

This results in an (IMO) simpler algorithm, results in fewer splits, and
is more amenable to delta handling (there is no reason to mutate the tree
at all when adding a delta to a position that already exists in the tree).

(but simple!) datastructures in the rewriter with a more complex but
more efficient one.

This replaces the Deltas vector with a specialized BTree that makes
delta lookups much more efficient.  This speeds up -emit-html on a 500K
.i file from 157.154 to 27.127 seconds on my machine (5.8x).

While this code is functional, it isn't very pretty, I have much 
refactoring planned for it, and will remove the USE_VECTOR ifdef.
Stay tuned.
