Commit Message

show: print a `Symbol` without the expression printer (#64448)

`show(io, ::Symbol)` called `show_unquoted_quote_expr`, whose `value`
argument is `@nospecialize`d: the Symbol branch is all a Symbol needs,
but every specialization of `show` for a Symbol also compiled the branch
for expressions, and with it the whole AST printer working on `Any`.
That made `repr(::Symbol)` (and anything showing a value that contains a
Symbol) fail `juliac --trim=safe` verification with hundreds of
unresolved calls.

Move the Symbol branch into `show_quoted_sym(io, ::Symbol)`, called by
both `show(io, ::Symbol)` and `show_unquoted_quote_expr`. The printed
text is unchanged.

Assisted-by: Claude Code (Opus 5.5)
