SymbolDatabase: handle method with unknown macro 'void f() MACRO {..}'
Fixed #5041 (Improve check: support 'auto' for 'Iterator used after element has been erased')
Tokenizer:simplifyMathFunction: added support for [ll]div() functions and corresponding unittests. The simplifcation is only performed, if a division by 1 is detected.
Fixed #5049: new check: (warning) Comparison of two identical variables with isgreater(result,result) evaluates always to false.
zero division or useless condition: dont crash when variable declaration is not parsed correctly
CheckIO: Clarify format check warnings
Fixed #4929 (false positive: Division by zero (standard function div()))
checkother:checkComparisonFunctionIsAlwaysTrueOrFalse: Removed redudant varid != 0 check. No functional changes.
Improved simplifyMathFunctions when simplifying special cases of pow(x,y)-function.
CheckIO: Fixed false positive when using wchar_t (#5051)
Fixed #5054 (debug warnings when Variable::typeStartToken() or Variable::typeEndTypen() is not set correctly)
MathLib: improved constness of local variables. No functional change.
