several patches.  These patches fix a problem
where templated types were not being completed the
first time they were used, and fix a variety of
minor issues I discovered while fixing that problem.

One of the previous local patches was resolved in
the most recent Clang, so I removed it.  The others
will be removed in due course.

This patch fixes all of the warnings due to unordered initialization lists.

Patch by Marco Minutoli.

 - Sema is now exported (and there was much rejoicing.)

 - Storage classes are now centrally defined.

Also fixed some bugs that the new LLVM picked up.

The goal is to separate the parser's data from the data
belonging to the parser's clients.  This allows clients
to use the parser to obtain (for example) a JIT compiled
function or some DWARF code, and then discard the parser
state.

Previously, parser state was held in ClangExpression and
used liberally by ClangFunction, which inherited from
ClangExpression.  The main effects of this refactoring 
are:

- reducing ClangExpression to an abstract class that
  declares methods that any client must expose to the
  expression parser,

- moving the code specific to implementing the "expr"
  command from ClangExpression and
  CommandObjectExpression into ClangUserExpression,
  a new class,

- moving the common parser interaction code from
  ClangExpression into ClangExpressionParser, a new
  class, and

- making ClangFunction rely only on
  ClangExpressionParser and not depend on the
  internal implementation of ClangExpression.

Side effects include:

- the compiler interaction code has been factored
  out of ClangFunction and is now in an AST pass
  (ASTStructExtractor),

- the header file for ClangFunction is now fully
  documented,

- several bugs that only popped up when Clang was
  deallocated (which never happened, since the
  lifetime of the compiler was essentially infinite)
  are now fixed, and

- the developer-only "call" command has been
  disabled.

I have tested the expr command and the Objective-C
step-into code, which use ClangUserExpression and
ClangFunction, respectively, and verified that they
work.  Please let me know if you encounter bugs or
poor documentation.
