Are you sure?
config/rs6000/rs6000.c has:
static tree
rs6000_builtin_conversion (unsigned int tcode, tree type)
rs6000 target is also a member of vect_intfloat_cvt in target-supports.exp.
Please note, that the testcase in Comment #0 is wrong, relevant cases in the
testsuite are gcc.dg/vect/vect-intfloat-conversion-X.c and
gcc.dg/vec/vect-floatint-conversion-X.c
