Swap the action and jmpbuf arguments to GTM_longjmp

On several ABIs, the first register parameter is the same as
the return value register. Moving the action parameter first
avoids the need for register shuffling on these targets.

* beginend.c (_ITM_abortTransaction): Update to match.
(GTM::gtm_thread::restart): Likewise.
