    Allow tree-ssa.exp to be run by itself
    
    tree-ssa testcases sometimes check autovect effective target
    but does not set it up.  On MIPS, those testcases fail with
    some TCL error messages.  This fixes the issue by calling
    check_vect_support_and_set_flags inside tree-ssa.exp.
    There might be other .exp files which need to be done this
    way too but I have not checked all of them.
    
    Tested on x86_64-linux-gnu and a cross to mips64-octeon-linux-gnu.
    Both full run of the testsuite and running tree-ssa.exp by itself.
    
    testsuite/ChangeLog:
    * tree-ssa.exp: Set DEFAULT_VECTCFLAGS and DEFAULT_VECTCFLAGS.
    Call check_vect_support_and_set_flags also.
