Refactorizations in class Token: changed handling of different types of tokens.
...
- Replace _isNumber, _isName, _isBoolean attributes by a single _type attribute (enum Token::Type), because not two of the old booleans could be true at the same time.
-> Add support for lots of different other kinds of tokens. (More precise checking of token type possible)
-> Replaced instant checking of type for Operators, etc. by a value calculated at creation time. (Faster checking)

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 = { ... }'.

Tokenizer: improve code and remove redundant checks.
...
In particular: improve 'double sharp' concatenation by handling also code which begins without the [{};]. Do the same with C# code. Also, in the labels simplification function, skip also '{}' when the open bracket is after a '='.
