Tokenizer::removeRedundantCondition: refactoring due to various reasons.
...
1) Remove the dead code with 'eraseDeadCode', not with 'eraseTokens' because of the possible presence of labels.
2) It's impossible that in tokenizer there is pattern like 'if (true|false) {code;} else if (cond) {code_cond;}' because the function 'Tokenizer::elseif' adds '{' between 'else' and 'if', hence a code path is redundant, so it's removed from code.

symbol database: add preliminary support for throw/catch block scopes. Just like the rest of cppcheck, ... is not handled properly for variables. Deep namespaces are also not handled properly yet. This is not an issue because this new capability is not used by any checks so it should be harmless.
