    testsuite: Fix gcc.dg/vect/tsvc tests on NetBSD
    
    All gcc.dg/vect/tsvc tests FAIL on NetBSD like
    
    FAIL: gcc.dg/vect/tsvc/vect-tsvc-s000.c (test for excess errors)
    UNRESOLVED: gcc.dg/vect/tsvc/vect-tsvc-s000.c compilation failed to produce executable
    UNRESOLVED: gcc.dg/vect/tsvc/vect-tsvc-s000.c scan-tree-dump-times vect "vectorized 1 loops" 1
    
    Excess errors:
    gcc.dg/vect/tsvc/tsvc.h:199:20: error: implicit declaration of function 'memalign' [-Wimplicit-function-declaration]
    gcc.dg/vect/tsvc/tsvc.h:199:10: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
    gcc.dg/vect/tsvc/tsvc.h:200:11: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
    
    While NetBSD lacks memalign, it has posix_memalign instead.
    
    Tested on amd64-pc-netbsd10.1 and i386-pc-solaris2.11.

            gcc/testsuite:
            * gcc.dg/vect/tsvc/tsvc.h (init): Don't use memalign on NetBSD.
