and Materialize/Read instead of using specializations of SerializeTrait<>. The
resulting code is much cleaner. We are also setting the stage so that only the
parts of the IdentifierTable that are ever referenced within the ASTs are
serialized, and not the whole table.

instead of just using "unsigned".  This gives us more flexibility in changing
the definition of the handle later, and is more self-documenting.

Added tracking of block stack in the Deserializer.  Now clients can query
if they are still within a block using the methods GetCurrentBlockLocation()
and FinishedBlock().

Implemented serialization of ConditionalOperator.
Implemented serialization of StmtExpr.
Fixed bug in serialization of IndirectGoto (did not properly serialize subexpression).

Rewrite RewriteObjCStringLiteral(). This version is simpler (and unlike the previous one, works:-)

If both parts of smul_lohi, etc. are used, don't simplify. If only one part is used, try simplify it.

Add the majority of machine-level critical edge breaking pass.  Most of this was written by Fernando, cleanup and updating to TOT by me.

This still needs a bit of work, particularly to handle jump tables properly.

backing a rewrite buffer than using an std::vector<char>.  This class was hacked
together very quickly and needs to be cleaned up, but it seems to work.  It speeds
up rewriting a a 7M file from 6.43s to 0.24s on my machine.  The impl could also
be made to be a lot more algorithmically sound.

This produces identical output to using vector on this testcase, if it causes a
problems or bugs are encountered, it can be disabled by changing the 
RewriteBuffer::Buffer typedef back.

Disable rewrite-tabs.  This speeds up processing of the commentified huge
crazy testcase steve gave me from 20s to 6.6s in a release build.

The trick is that text replacement should go after the insert point, 
not before it, because it will be replacing text after the point, not before 
it.
