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.
