[PATCH 3/5] testsuite: Add vect_perm3_int guards

SLP vectorisation of gcc.dg/vect/fast-math-vect-call-1.c involves a group of 3 floats, which requires the same permutation as vect_perm3_int. The load/store_lanes XFAILs in gcc.dg/vect/slp-perm-6.c implicitly assumed vect_perm3_int, which is true for Advanced SIMD but not for VLA SVE. Whether it'
