    Converts a collection of Stone specifications into the intermediate
    representation used by Stone backends.

    The process is: Lexer -> Parser -> Semantic Analyzer -> IR Generator.

    The code is structured as:
        1. Parser (Lexer embedded within)
        2. IR Generator (Semantic Analyzer embedded within)

    :type specs: List[Tuple[path: str, text: str]]
    :param specs: `path` is never accessed and is only used to report the
        location of a bad spec to the user. `spec` is the text contents of
        a spec (.stone) file.

    :raises: InvalidSpec

    :returns: stone.ir.Api
