[testsuite] Fix vect_widen_mult_si_to_di_pattern on non-x86/ia64 targets

[Rainer Orth]

The new gcc.dg/vect/pr60656.c test errors out on non-x86/ia64 targets:

ERROR: gcc.dg/vect/pr60656.c: error executing dg-final: can't read 
"et_vect_widen_mult_si_to_di_pattern_saved": no such variable
UNRESOLVED: gcc.dg/vect/pr60656.c: error executing dg-final: can't read 
"et_vect_widen_mult_si_to_di_pattern_saved": no such variable
ERROR: gcc.dg/vect/pr60656.c -flto -ffat-lto-objects: error executing dg-final: 
can't read "et_vect_widen_mult_si_to_di_pattern_saved": no such variable
UNRESOLVED: gcc.dg/vect/pr60656.c -flto -ffat-lto-objects: error executing

variable

The following patch fixes this.  Tested with the appropriate runtest
invocations on sparc-sun-solaris2.11 and i386-pc-solaris2.11, installed
on mainline.

Ok for 4.9 branch, too?

Thanks.

        * lib/target-supports.exp
        (check_effective_target_vect_widen_mult_si_to_di_pattern):
        Initialize et_vect_widen_mult_si_to_di_pattern_saved.
        Fix formatting.
