TranslationUnit now owns IdentifierTable, TargetInfo, and Selectors objects
...
when it is constructed via deserialization. This is done by recording a flag
indicating that this is the case, and it deletes these objects by getting
the references stored in the ASTContext object. This fixes some memory
leaks that occurs when we deserialize translation units from bitcode files.
The rationale between having TranslationUnit sometimes own these objects and
sometimes not is that a TranslationUnit object can be constructed from
state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus
in these cases won't own the IdentifierTable or Selectors, etc. During
deserialization, there is no Preprocessor, so somebody needs to own these
objects in order for them to be properly reclaimed.

in a block's terminator. This expression is visited within a block, but it is accessed by the
terminator. This is important to observe because for live-variables analysis the block-level
expression is live between the terminator and where the expression occurs in the block. So far
this hasn't been an issue to not observe this because the block-level expression used in the
terminator is always the last one in the block, and we have never queried the liveness information
about this point (but before the terminator).

HTMLDiagnostics now uses the new "getCanonicalID()", "isFromMainFileID()" methods from

SourceManager when doing HTML pretty-printing. This resolves an insidious bug when

Added "getCanonicalID()", "isFromSameFile", and "isFromMainFile" to compare

the files of different SourceLocations. These methods correctly handle the
case where a file may have multiple FileIDs due to it being large enough
to be spread across several chunks.

Change the RewriteRope::Chunks data structure from an std::list into
...
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.

This patch adds very basic support for parsing and type-checking class
...
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).

This patch is just the easy part of the class names patch, which
...
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;

Change the btree algorithm to split nodes bottom-up instead of top-down.

Do an initial hack at replacing one of the incredibly inefficient
...
(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.
