Subject: Use sigsetjmp/siglongjmp in opcodes

sigsetjmp/siglongjmp without saving the signal mask is faster than
setjmp/longjmp on systems where the signal mask is saved.  This patch
uses sigsetjmp/siglongjmp without saving the signal mask if possible.

	PR binutils/16886
	* config.in: Regenerated.
	* configure: Likewise.
	* configure.in: Check if sigsetjmp is available.
	* h8500-dis.c (private): Replace jmp_buf with OPCODES_SIGJMP_BUF.
	(fetch_data): Replace longjmp with OPCODES_SIGLONGJMP.
	(print_insn_h8500): Replace setjmp with OPCODES_SIGSETJMP.
	* i386-dis.c (dis_private): Replace jmp_buf with OPCODES_SIGJMP_BUF.
	(fetch_data): Replace longjmp with OPCODES_SIGLONGJMP.
	(print_insn): Replace setjmp with OPCODES_SIGSETJMP.
	* ns32k-dis.c (private): Replace jmp_buf with OPCODES_SIGJMP_BUF.
	(fetch_data): Replace longjmp with OPCODES_SIGLONGJMP.
	(print_insn_ns32k): Replace setjmp with OPCODES_SIGSETJMP.
	* sysdep.h (OPCODES_SIGJMP_BUF): New macro.
	(OPCODES_SIGSETJMP): Likewise.
	(OPCODES_SIGLONGJMP): Likewise.
	* vax-dis.c (private): Replace jmp_buf with OPCODES_SIGJMP_BUF.
	(fetch_data): Replace longjmp with OPCODES_SIGLONGJMP.
	(print_insn_vax): Replace setjmp with OPCODES_SIGSETJMP.
	* xtensa-dis.c (dis_private): Replace jmp_buf with
	OPCODES_SIGJMP_BUF.
	(fetch_data): Replace longjmp with OPCODES_SIGLONGJMP.
	(print_insn_xtensa): Replace setjmp with OPCODES_SIGSETJMP.
	* z8k-dis.c(instr_data_s): Replace jmp_buf with OPCODES_SIGJMP_BUF.
	(fetch_data): Replace longjmp with OPCODES_SIGLONGJMP.
	(print_insn_z8k): Replace setjmp with OPCODES_SIGSETJMP.
