I don't like this TEST_COND_gt_binary64.
If the condition combines TEST_LDOUBLE with something about mantissa bits
or exponents for long double, only the thing about mantissa bits or
exponents is actually needed. If it's TEST_LDOUBLE on its own (or
combined with conditions on integer types rather than on long double), as
in e.g. tests of ceil, then testing for >= 64 mantissa bits is sufficient
(the tests may actually only require some number between 53 and 64, but
testing for >= 64 seems reasonable). That is, TEST_LDOUBLE on its own can
be treated as defined TEST_LDOUBLE && LDBL_MANT_DIG >= 64.
