  Reland "[llvm-exegesis] Set stack pointer register after starting perf counter (#72489)"

This reverts commit 52b4b357268ac114f7972e37da1e5954f322df09.

This commit was causing build failures on bots without libpfm installed
as the CHECK requires were not set correctly. The test added should only
run on machines with libpfm enabled due to the limitations currently
imposed by the subprocess execution mode.
