Log:
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.

        * libitm_i.h (GTM_longjmp): Swap first and second arguments.
        * beginend.c (_ITM_abortTransaction): Update to match.
        (GTM::gtm_thread::restart): Likewise.
        * config/alpha/sjlj.S (GTM_longjmp): Likewise.
        * config/x86/sjlj.S (GTM_longjmp): Likewise.
