t_ilogb: Nix spurious line break in ATF_CHECK_MSG.

tests/lib/libm/t_ilogb: Expand and tidy.

1. Instead of calling out VAX by name, use #ifdef NAN and
   isinf(INFINITY).  (VAX defines INFINITY even though it's not an
   infinity, not sure if there's a better compile-time test.)

2. Verify ilogbl works on long double on all architectures, not just
   those with __HAVE_LONG_DOUBLE which means long double is _larger_
   than double.

Test for FE_INVALID in a way that works for powerpc too.

powerpc seems to return FE_INVALID | FE_VXSOFT rather than just FE_INVALID.
XXX need extra careful reading of standards

Mistakes were made, compare correct values now.

ilogb(INFINITY)=-INT_MAX, it should be INT_MAX

while here, test raised exceptions, other values.

XXX some platforms don't have exceptions
