[llvm-exegesis] Align loop MBB in loop repetitor (#77264)
This patch sets the alignment of the loob MBB in the loop repetitor to
16 to avoid instruction fetch/predecoding bottlenecks that can come up
with unaligned code. The value of 16 was chosen based on numbers for
recent Intel microarchitectures and reccomendations from Agner Fog.
Fixes #77259.
