Pete Johns 78795dc3ac Fix false positive: Misused Scope Object does not pick constructors of local class declarations.
It does pick up if there is an unused construction within the function, though.

Pete Johns 6e0ef3eda2 Fixed #1132 (Detection of misused scope objects in functions)
Emits error in the form:

    [useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately

    ...if an instance of a class or struct is unnamed and therefore destroyed
    straight after creation.

    Only checks for misused scope objects within functions.

    Optimised isIdentifierObjectType() by memoizing.

Pete Johns c6acdccfa0 Fixed #1132 (Detection of misused scope objects)
Emits error in the form:

    [useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately

...if an instance of a class or struct is unnamed and therefore destroyed
straight after creation.

Removed "internal error" from token.cpp, since in this case varid would be NULL.

Daniel Marjamäki f843678a07 Redundant conditions: some refactorings
* removed the 'redundant null pointer' check. sometimes it's unsafe to delete NULL pointer. and this check doesn't point out errors anyway.
 * moved the 'redundant condition' check for set::remove. Moved it to CheckStl.
