E.g. during inlining new symbol name can be duplicated and then `ValueSymbolTable::makeUniqueName()` will add unique suffix, exceeding the `non-global-value-max-name-size` restriction. Also fixed `unsigned` type of the option to `int` since `ValueSymbolTable`' constructor can use `-1` value that means unrestricted name size.
