git_commit commit 8dae17be2991cd7f0d7fd9aa5aecd064520a14f6

[libc++] Refactor memory allocation in basic_string (#128423)

This patch introduces a string-internal API to make the allocation and
deallocation the long string simpler. Before this we had a lot of code
duplication, so ensuring that things were actually correct was
non-trivial.
