New target check: vect_long_mult
We don't have a 64 bit vector integer multiply on z. Add a specific
check for that.
gcc/ChangeLog:
2017-10-04 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* doc/sourcebuild.texi: Document vect_long_mult.
gcc/testsuite/ChangeLog:
2017-10-04 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* gcc.dg/vect/pr60656.c: Check vect_long_mult.
* lib/target-supports.exp (check_effective_target_vect_long_mult):
New proc.
