[PATCH] testsuite: require avx_runtime for some tests

[Marc Poulhiès]

These 3 tests fails parsing the 'vect' dump when not using -mavx. Make
the dependency explicit.

gcc/testsuite/ChangeLog:

        * gcc.dg/vect/vect-ifcvt-18.c: Add dep on avx_runtime.
        * gcc.dg/vect/vect-simd-clone-16f.c: Likewise.
        * gcc.dg/vect/vect-simd-clone-18f.c: Likewise.
---
Tested on x86_64-linux and x86_64-elf.

Ok for master?
