Subject: PR rtl-optimization/51771: revert TM returns twice kludge

As mentioned in the PR, this seems to no longer be an issue after we redesigned the TM abnormal edges (in the uninstrumented code path patchset).

Tested with the STAMP benchmark for both 1 and 4 threads, as well as with the GCC regression suite.

OK for trunk?
