e2ef6e380b Updated to latest LLVM. Major LLVM changes:
- 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.

9e6ed53ea5 Bugfixes to the expression parser. Fixes include:
- If you put a semicolon at the end of an expression,
   this no longer causes the expression parser to
   error out.  This was a two-part fix: first,
   ClangExpressionDeclMap::Materialize now handles
   an empty struct (such as when there is no return
   value); second, ASTResultSynthesizer walks backward
   from the end of the ASTs until it reaches something
   that's not a NullStmt.

 - ClangExpressionVariable now properly byte-swaps when
   printing itself.

 - ClangUtilityFunction now cleans up after itself when
   it's done compiling itself.

 - Utility functions can now use external functions just
   like user expressions.

 - If you end your expression with a statement that does
   not return a value, the expression now runs correctly
   anyway.

Also, added the beginnings of an Objective-C object
validator function, which is neither installed nor used
as yet.

afa4237d9b Fixed an expression parser bug that prevented
certain functions from being resolved correctly.

Some functions (particularly varargs functions)
are BitCast before being called, and the problem
was that a CallInst where getCalledValue()
returned a BitCast ConstantExpr was not being
relocated at all.

This problem should now be resolved for the case
of BitCast.

8e999e4015 Added code to run pointer validation checks in
expressions.  If an expression dereferences an
invalid pointer, there will still be a crash -
just now the crash will be in the function
___clang_valid_pointer_check().

6961e87847 Added support for dynamic sanity checking in
expressions.  Values used by the expression are
checked by validation functions which cause the
program to crash if the values are unsafe.

Major changes:

- Added IRDynamicChecks.[ch], which contains the
  core code related to this feature

- Modified CommandObjectExpression to install the
  validator functions into the target process.

- Added an accessor to Process that gets/sets the
  helper functions
