Detailed Description

An IOptionPragmaParser implementation that supports basic pragmas that all backends can support.

P4COptionPragmaParser recognizes:

• pragma diagnostic [diagnostic name] [disable|warn|error]
• @diagnostic([diagnostic name], ["disable"|"warn"|"error"])

Backends that want to add support for additional pragmas will usually want to inherit from this class and delegate tryToParse() to the superclass if they're unable to parse a pragma.
