Fix ICE: in function_and_variable_visibility, at ipa-visibility.c:795 [PR99466]
In get_emutls_init_templ_addr, only thread-local declarations that were
DECL_ONE_ONLY would have a public initializer symbol, ignoring variables
that were declared with __attribute__((weak)).
gcc/ChangeLog:
PR ipa/99466
* tree-emutls.c (get_emutls_init_templ_addr): Mark initializer of weak
TLS declarations as public.
gcc/testsuite/ChangeLog:
PR ipa/99466
* gcc.dg/tls/pr99466-1.c: New test.
* gcc.dg/tls/pr99466-2.c: New test.
