Incomplete parse of pattern (A.6.7.1)

[bryceberger]

dalance/svlint#296 (comment)

sv-parser rejects the following code:

module M();
  always_comb
    if (a matches (tagged Jmp .j))
               // ^ doesn't like this paren
      b = 1;
endmodule

The relevant section in IEEE 1800-2023 is A.6.7.1 Patterns, which contains the following rule:

pattern ::=
    '(' pattern ')'
  | ... rest of definition
