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.

simplifyIfAddBraces: Remove restriction for jumping opening parenthesis '(' as a fix to #2873 , because even without this the original test case doesn't crash anymore. Add more jumping patterns.
...
simplifyFunctionParameters: Add more jumping patterns and an observation related to error message for equal parameter names, help needed.
Fix grammar mistake in comment.

Other improvements to tokenizer code.
...
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 = { ... }'.
