Add initial implementation of scan-view
 - Web based interface to static analyzer.

Add REPORTBUG marker to scan-build.

Test case for transfer function logic of const casts.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56369 91177308-0d34-0410-b5e6-96231b3b80d8

Bug fix: for the base transfer function logic for casts, handle const casts as just propagating the value.

Update checker build

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56367 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed logic error in BasicConstraintManager pointed out by Zhongxing Xu.

For checking if a symbol >= value, we need to check if symbol == value || symbol
> value. When checking symbol > value and we know that symbol != value, the path
is infeasible only if value == maximum integer.

For checking if a symbol <= value, we need to check if symbol == value || symbol
< value. When checking symbol < value and we know that symbol != value, the path
is infeasible only if value == minimum integer.

Updated test case exercising this logic: we only prune paths if the values are
unsigned.

Fix rdar://6222856: the receiver of a message expr is an
arbitrary expr, not just a assign expr.  The grammar comment
was right, the code was just wrong.

When we have a binary expression 'int operator symbol', properly rewrite this as
'symbol operator-reverse int'. This patch is a combination of code from
Zhongxing Xu and myself (Zhongxing noticed this bug for the cases of
relational operators).
