Please backport commit 100888fb6d8a185866b1520031ee7e3182b173de from the upstream kernel.

We are updating clang to version 18 in REHL 8.10, and pyperf180.c needs a fix from upstream in order to compile with clang-18. This patch does not change the functionality of the test at all, it addresses the fact that the BPF tests are very sensitive to changes in the clang optimizers especially around loop unrolls.
