New Revision: cc4ecfd68b79a44f101fe9924d088a83477797c0

DIFF: https://github.com/llvm/llvm-project/commit/cc4ecfd68b79a44f101fe9924d088a83477797c0.diff

LOG: [ADT] Rename SmallString::{starts,ends}with to {starts,ends}_with (#74916)

This patch renames {starts,ends}with to {starts,ends}_with for
consistency with std::{string,string_view}::{starts,ends}_with in
C++20.  Since there are only a handful of occurrences, this patch
skips the deprecation phase and simply renames them.
