<!--LLVM PR SUMMARY COMMENT-->
@llvm/pr-subscribers-libcxx
Author: Louis Dionne (ldionne)
<details>
<summary>Changes</summary>
The <__locale> header was a collection of distinct utilities. This patch splits it up into granular headers under __locale_dir/. This patch however does not use the granular headers from users of <__locale>: this will be done in a separate patch.
