This reverts commit c861fe8a71e64f3d2108c58147e7375cd9314521. Unfortunately, this use of hidden visibility attributes causes user-defined specializations of standard-library types to also be marked hidden by default, which is incorrect. See discussion thread on #131156. ...and also reverts the follow-up commits: Revert "[libc++] Add explicit ABI annotations to functions from the block runtime declared in <__functional/function.h> (#140592)" This reverts commit 3e4c9dc299c35155934688184319d391b298fff7. Revert "[libc++] Make ABI annotations explicit for windows-specific code (#140507)" This reverts commit f73287e623a6c2e4a3485832bc3e10860cd26eb5. Revert "[libc++][NFC] Replace a few "namespace std" with the correct macro (#140510)" This reverts commit 1d411f27c769a32cb22ce50b9dc4421e34fd40dd.
