I think these variables should have names starting "double-" to reflect
that they are for tests for double (there's no particular reason, if
vector functions for float are added in future, for them to use the same
flags for a given vector length as double tests; it's quite plausible
float-vlen4 and double-vlen2 would use the same flags, being for the same
bit-length of vectors).
