- Make Token::isExtendedOp() returning also true for all assignment and ++/-- operators

- fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522 )):
> "lib/checkmemoryleak.cpp", line 578: Warning (Anachronism): Formal argument __compar of type extern "C" int(*)(const void*,const void*) in call to bsearch(const void*, const void*, unsigned long, unsigned long, extern "C" int(*)(const void*,const void*)) is being passed int(*)(const void*,const void*).
- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)
- fix word misspellings (mostly comments, a few output lines)
- Parenthesis => Parentheses (both variations were used in the codebase)
- fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():
```
- "An unsigned variable will never alwayw be positive so it is either pointless or "
+ "An unsigned variable can't be negative so it is either pointless or "

new simplify: 'code ; ({ some_code ; });' to 'code ; some_code ;';
remove the sanity check in checkunusedvar, so when it crashes again it's easy to spot a bigger problem;
'internal' reported 'Token::Match' with simple pattern.
'Tokenizer::tokenize()' refactorings:
make one loop with many simple simplifications instead of many loops with one simplification.
