This is just for use in the debugger when one may want to know what is in the
current scope. The order is not guaranteed but at least it can provide /some/
info ignoring that property. These are no-ops when not in asserts and I put in a
compile time warnign to make sure it is not used in the actual code base.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

- Added missing ifdef guard in PointerIntEnum header
- Consistent naming convention for ifdef guards
- Consistent 'end namespace swift'
- Consistent single EOL at end of header files
Create a scope for each case block to contain bindings from its patterns, and invoke addVarsToScope after parsing case label patterns to introduce vars into that scope. Refactor addVarsToScope to use an ASTWalker so it finds pattern vars embedded in expr patterns.

In order to do this, we need to save and restore parser state easily. The
important pieces of state are:
* lexer position;
* lexical scope stack.
Lexer position can be saved/restored easily. We don't need to store the tokens
for the function body because swift does not have a preprocessor and we can
easily re-lex everything we need. We just store the lexer state for the
beginning and the end of the body.
To save the lexical scope stack, we had to change the underlying data
structure. Originally, the parser used the ScopedHashTable, which supports
only a stack of scopes. But we need a *tree* of scopes. I implemented
TreeScopedHashTable based on ScopedHashTable. It has an optimization for
pushing/popping scopes in a stack fashion -- these scopes will not be allocated
on the heap. While ‘detached’ scopes that we want to re-enter later, and all
their parent scopes, are moved to the heap.
In parseIntoTranslationUnit() we do a second pass over the 'structural AST'
that does not contain function bodies to actually parse them from saved token
ranges.
