ieee754-h tests: Fix some gcc -Wmissing-field-initializers warnings

[Bruno Haible]

These two warnings

test-ieee754-h.c:39:4: warning: missing initializer for field 'frac_lo' of 
'const struct <anonymous>' [-Wmissing-field-initializers]
test-ieee754-h.c:40:4: warning: missing initializer for field 'frac_lo' of 
'const struct <anonymous>' [-Wmissing-field-initializers]

are probably consequences of copy&paste, thus unintended. This patch fixes them.

        ieee754-h tests: Fix some gcc -Wmissing-field-initializers warnings.
        * tests/test-ieee754-h.c (float_tests): Use float literals.
        (double_tests): Use double literals. Initialize frac_lo.
