Apply UsualUnaryConversion() to statement conditions that expect scalars.
UsualUnaryConversion() converts function/arrays to pointers.
This fixes the following...
int func() {
int A[10];
while (A) {
}
if (A) ;
for (; A; ) ;
}

- ParseForStatement(): Put back a test/assignment. My removal of
ParseExprStmt() was a bit over zealous:-(thanks to Chris for pointing it out)
- Add assert to VisitDeclStmt().
- Removed an out-of-date FIXME
- Added some curlies for a couple multi-line calls to Diag().

- Many tweaks to various diagnostics.
- Fixed some location/range issues.
- Bug fix to Sema::ParseDeclStmt() - error return code is "true", not 0.

Implement some FIXME's that stand in the way of fully typechecking "for"
statements. This involved:
- Adding a DeclStmt AST node (with statement visitor). The DeclStmt
printer is preliminary.
- Added a ParseDeclStmt action, called from Parser::ParseForStatement()
and Parser::ParseStatementOrDeclaration(). DID NOT add to
Parser::ParseIdentifierStatement()...probably could have, however didn't
really understand the context of this rule (will speak with Chris).
- Removed ParseExprStmt (and it's clients)...it was vestigial.

- Finished Sema::ParseReturnStmt(). Still need to tweak ranges.
- Tweaked location for function arguments (they now point at the expression directly, no parens or commas).
- Added InvalidOperands helper...was sick of looking at the same 3 lines in ~9 Check functions.
- Added a few diags and moved a group of statement diags to the proper comment/category.

the label identifier. Handle fwd references etc. This allows us to detect
uses of undefined labels and label redefinitions, such as:
t.c:2:12: error: redefinition of label 'abc'
abc: ; abc:

t.c:2:3: error: previous definition is here
abc: ; abc:

t.c:12:12: error: use of undeclared label 'hijl'
goto hijl;

Reviewed by:
- Added type checking to Sema::ParseReturnStmt (still under construction).
- Improved Expr::isLvalue() and Expr::isModifiableLvalue() to return more
info. Used the info in Sema::CheckAssignmentOperands() to produce more
descriptive diagnostics. Added FIXME to other clients of isLvalue()/etc.
- Added a SourceLocation slot to MemberExpr...changed the implementation
of getSourceRange().
- Added getResultType() helper to FunctionDecl.
- Changed many Diag calls to use the SourceRange support (now that it's
a big hit...we better milk it:-).

Extended Expr's constant expression predicates to return a source location
if the predicate returns false. This enables us to position the cursor

Reviewed by:
- Added Sema::isConstantArrayType() and Type::isConstantSizeType().
- Implemented type checking for "variably modified" types (i.e. VLA's).
Added checking for file scope variables, static variables, member variables,
and typedefs.
- Changed Expr::isIntegerConstantExpr() to non-virtual implementation.
Fixed bug with sizeof/alignof. Looking at the diff, I may need to
add a check to exclude alignof.
- Added Expr::isConstantExpr()...non-virtual, like above.
- Added typechecking for case statements (found a bug with actions/parsing...).
- Added several diagnostics.
- Fixed several comments.
Started implemented constant expression checking for arrays.
