+Subject: [PATCH] Remove APInt/APSInt toString() std::string variants
+
+clang 13+ has removed this in favour of a pair of llvm::toString
+() helpers inside StringExtras.h to improve compile speed by avoiding
+hits on <string> header
+
+Upstream-Status: Submitted [https://github.com/iovisor/bcc/pull/3488]
