PKEuS 2ace3d3144 Rewritten handling of declaration specifiers:
- Removed simplifyConst() because it did the opposite of the (superior) simplifyStaticConst()
- Execute simplifyStaticConst() in simplifyTokenList1() - there is no reason to defer it, and it is required to properly parse declarations like "unsigned static int i;"
- Fixed simplifyStaticConst() to handle more patterns. It did not work at the beginning of the token list and for function arguments
- Reimplemented Tokenizer::simplifyStdType()
-> properly support all possible ways to declare integers as requested by the standard, instead of only a few common permutations of "unsigned|signed", "short|char|long|int"
-> Fixed parsing of _Complex/complex types
