C++: Support noexcept operator
The code model failed to parse the noexcept operator which is often
used in noexcept specifiers, e.g.: "void f() noexcept(noexcept(g()));"
Consequently some c++11 headers such as unordered_map, array
and unordered_set could not be parsed and no code completition was
available. I have created the NoExceptOperatorExpressionAST class
which is created whenever a noexcept token is found in an
expression with operator precedence. The noExcept test case
in the cplusplus/cxx11 test now contains a function that
uses the noexcept operator.
Fixed noexcept operator parsing
Added the test requested by Sergey Shambir, which then revealed that
i had not implemeneted the noexpect operator parsing according to the
c++ specification.
As stated here http://cpp0x.centaur.ath.cx/expr.unary.noexcept.html
the noexcept operator is a unary-expression that contains an
expression (and not a constant-expression). This should now be fixed.
