Darwin: Anchor block internal symbols must not be linker-visible.
When we are using section anchors, there's a requirement that the
sequence of the content is an unbroken block. If we allow linker-
visible symbols in that block, ld(64) would be able to break it
into sub-sections on those symbol boundaries.
Do not allow symbols that should be visible to be anchored.
Do not make anchor block internal symbols linker-visible.
gcc/ChangeLog:
* config/darwin.cc (darwin_encode_section_info): Do not
make anchored symbols linker-visible.
(darwin_use_anchors_for_symbol_p): Disallow anchoring on
symbols that must be linker-visible (or external), even
if the definitions are in this TU.
