Add autoconf test to detect x87-style double rounding, as described in
issue #2937. This information can be helpful for diagnosing platform-
specific problems in math and cmath. The result of the test also
serves as a fairly reliable indicator of whether the x87 floating-point
instructions (as opposed to SSE2) are in use on Intel x86/x86_64 systems.

isinf and isnan are macros, not functions; fix configure script
to use AC_CHECK_DECLS instead of AC_CHECK_FUNCS for these.
(See discussion in issue #4506)
