Improve support for labels in simplifyAddBraces step (#3278)
Previously only a single regular label before a compound statement was
allowed in simplifyAddBracesPair() after if/switch/do/while/for.
This patch adds support for:
* case-labels;
* labels before a single statement;
* labels before try/catch blocks;
* multiple consecutive labels.

Additionally the code for skipping a case label was extracted into a
separate function from simplifyLabelsCaseDefault() and reused in
simplifyAddBracesPair().

Fix varId assignment for uses of variables declared in the if condition (#3231)
Variables declared in the if condition (or in C++17 init-statement) are
visible not only in the if body but also in the else body. But logic in
Tokenizer::setVarIdPass1() handled such variables as if they were
declared in the if body.

As the result they were removed from variablesMap by the time the else
block was parsed and their uses in the else block were either given an
incorrect varId from variables in some outer scope or not given a varId
at all.

This then resulted in false positive unreadVariable errors for variables
declared in the if condition (or init-statement) and used only in the
else block.

Simplification from "else if ..." to "else { if ... }" was moved before
setVarId() to simplify detection for ends of blocks in if-else chains.

10221: Fix setVarId in template code (#3187)
The computation of the classname was not expecting templates. Simply
skipping the template part seems to fix the issue.

Fix tokenizing of x[i](0) (Fixes #8875) (#3167)
Fix faulty removal of parenthesis when "]" is followed by parenthesis
with a number inside, for example when calling a function pointer in
an array or (perhaps more common) in c++, calling operator ( on an
element in an array.

Fixes #8875 where such wrong simplification lead to a FP with too many
bits shifted due to "<<" was interpreted like a shift operator rather
than a stream output.

Robert Reif 3c6fae37e4 minor simplifyUsing optimizations
The using type aliases are a C++ 11 feature so only check for them in C++ 11 or later.

Don't try to simplify a type alias when it can't be parsed.
