- 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.

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

debugger to insert self-contained functions for use by
expressions (mainly for error-checking).
In order to support detecting whether a crash occurred
in one of these helpers -- currently our preferred way
of reporting that an error-check failed -- added a bit
of support for getting the extent of a JITted function
in addition to just its base.
