Don't crash when preparsing destructured arguments This adds the materialized literal count accumulated while parsing the parameters (in the parser proper) to that accumulated by the preparser. This should have been caught in cctest/test-parsing, but it's not covered because the parsing tests call directly into the preparser rather than using Parser::ParseFunctionLiteral (which fully-parses the parameters and then calls into the preparser to skip over the function body). Note that this further-inflates the materialized literal count for functions with destructured arguments, since some of the counted literals are actually binding patterns. But that's not specific to binding patterns in formal parameters: it happens in function bodies, too.
