  -----------
  [clang-tidy] Avoid bugprone-macro-parentheses warnings after goto argument

clang-tidy should not generate warnings for the goto argument without
parentheses, because it would be a syntax error.

The only valid case where an argument can be enclosed in parentheses is
"Labels as Values" gcc extension: https://gcc.gnu.org/onlinedocs/gcc/Labels-as-Values.html.
This commit adds support for the label-as-values extension as implemented in clang.

Fixes bugzilla issue 49634.
