Fix Valgrind error in arraySize():
...
if there's code like: 'int [ ] a = { 1 , 5 , }', 'end' is last '}', when 'tok2' arrives to second ',' and cppcheck finds out that next token to 'tok2' is '}', remove this ',' with 'tok2->deleteThis()' but it causes (maybe) a memory corruption to 'end' which will gave problems later because 'tok' will be assigned to it or its next token.

Tokenizer::simplifyDoWhileAddBraces:

1)rewrite fix for ticket #988 (just don't simplify inside macro parenthesis);
2)use a different organization of the code: start from last token and proceed backwards. This way 'simplifyDoWhileAddBracesHelper' can be called just once, hence the 'Helper' code can be improved and moved in the main function.

Handle SQL code better, even when there's no ';' after 'EXEC SQL'.
simplifyVarDecl: Check with 'Token::Match' once when you have to check a pattern inside which there should be a number or a variable. Use '%any%' and after that check if that string is a number or a variable name later.
simplifyGoto: process also anonymous structs and unions which should have 'indentspecial' incremented, skip code like 'var = { ... }'.

Refactor the same expression check
...
Work out if a function is inconclusive when creating the entry in the
Expressions class instead of when checking the counts at the end. Store
the result in a new bool flag in the ExpressionTokens helper struct.
The pointer to symbol database and ref to list of const functions are
temporarily stored in the Expressions helper class to avoid passing
them in too on every endExpr(tok) call.
Use a const reference to ExpressionTokens in the check loop to avoid
repeating the it->second several times, which clarifies what that code
does.

Fix ticket #3317 (same expression false positives)
...
Add a check for function calls that have no side effects. That means
known const methods and a list including strcmp, strlen, etc.
If the function is not known to be side effect-free then no style
warning is given.
Add test cases for the duplicate expressions.
