Subject: [PATCH] Review some attribute macro usage

* .dir-locals.el (c-noise-macro-names): Remove ANDROID_EXPORT, which
is no longer used.  Add ATTRIBUTE_COLD, ATTRIBUTE_CONST,
ATTRIBUTE_MAY_ALIAS, ATTRIBUTE_NONSTRING, ATTRIBUTE_RETURNS_NONNULL,
EXTERNALLY_VISIBLE, MAYBE_UNUSED, and NODISCARD.
(c-noise-macro-with-parens-names): Also tell cc-mode about some
function-like attribute macros in use (bug#80428).

* src/conf_post.h (RE_TRANSLATE_P): Remove; it is no longer used.
