On ARM, when GOARM<=6 the TLS pointer is fetched via a call to a kernel helper. This call clobbers LR, even just temporarily. If the function is NOFRAME, if a profiling signal lands right after the call returns, the unwinder will find the wrong LR. Not mark it NOFRAME, so the LR will be saved in the usual way and stack unwinding should work. May fix #52829.
