after a rough hack to allow complex type in both omp-simd-clone and
vectorizer(get_related_vectype_for_scalar_type), testcase in PR could be
compiled to
.L4:
vmovapd a(%rbx), %ymm0

Hmm, it's in i386.cc
23455/* Set CLONEI->vecsize_mangle, CLONEI->mask_mode, CLONEI->vecsize_int,
23456 CLONEI->vecsize_float and if CLONEI->simdlen is 0, also
23457 CLONEI->simdlen. Return 0 if SIMD

An alternative is taking vector complex as a 2*N length vector(just like
vectorizer did).
But __attribute__ ((__simd__ ("notinbranch"))) need to be extent for that.
