This patch adds assembly routines to enable setjmp/longjmp for aarch64
on linux.  It fixes:

 * test/tsan/longjmp2.cc
 * test/tsan/longjmp3.cc
 * test/tsan/longjmp4.cc
 * test/tsan/signal_longjmp.cc

I also checked with perlbench from specpu2006 (it fails to run
with missing setjmp/longjmp intrumentation).
