When `ValueObjectPrinter` calls its `m_decl_printing_helper`, not all state is
passed to
the helper. In particular, the helper doesn't have access to `m_curr_depth`,
and thus
can't act on the logic within `ShouldShowName`.
To address this, this change passes in a modified copy of `m_options`. The
modified copy
has has `m_hide_name` set according to the results of `ShouldShowName`. This
allows
helper functions to know whether the name should be shown or hidden, without
having
access to `ValueObjectPrinter`'s full state.
This is NFC in mainline lldb, as the only decl printing helper doesn't make use
of this.
However in swift-lldb at least, there are decl printing helpers that do need
this
information passed to them. See https://github.com/apple/llvm-project/pull/6795
where a
test is also included.
