Improves geomean of CTMark by a tiny bit (-0.06 % instruction count).
The idea was originally suggested here https://reviews.llvm.org/D93838#inline-983103 but fell through the cracks as it seems.

Hi Alexandros,
Linaro benchmarking CI flagged this patch. After it clang seems to miscompile 602.gcc_s from SPEC CPU2017 for "-O3 -flto" on aarch64-linux-gnu. Also, it appears that 600.perlbench_s slows down by 9%.
Could you investigate, please? Let me know if you need any assistance in reproducing the problem.
