syntax: adjust number literal parsing and string to number conversion
- Recognize new number literal prefixes `0o` and `0O` for octal as well
as `0b` and `0B` for binary number literals
- Treat number literals with leading zeros as octal while parsing but
as decimal ones on implicit number conversions, means `012` will yield
`10` while `+"012"` or `"012" + 0` will yield `12`
