9df6088ddd Revert "really fix #3527 (Internal error. Token::Match called with varid 0. Please report this to Cppcheck developers)" 
This reverts commit a37031944e5d26f169e2026aec182b5aae7bc88d.

I don't want this hard coding of macro names. Feel free to come with a more generic solution if you want.

0f1f3c0f5f 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.
