Dimitry Andric b451efbedc Resolve conflicts between macros in fenv.h and ieeefp.h
This is a follow-up to r321483, which disabled -Wmacro-redefined for
some lib/msun tests.

If an application included both fenv.h and ieeefp.h, several macros such
as __fldcw(), __fldenv() were defined in both headers, with slightly
different arguments, leading to conflicts.

Fix this by putting all the common macros in the machine-specific
versions of ieeefp.h.  Where needed, update the arguments in places
where the macros are invoked.

This also slightly reduces the differences between the amd64 and i386
versions of ieeefp.h.
