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.
