* libc/stdlib/ldtoa.c (_ldcheck): New routine
that categorizes a long double as NaN, Infinity, or other.
* libc/stdio/vfprintf.c [WANT_IO_LONG_DBL](_VFPRINTF_R): Removed
isinfl and isnanl static routines which were i386-specific. Changed
calls to the two removed routines to a single _ldcheck call.
* libc/stdio/vfieeefp.h (ldieee): Fixed missing semi-colons.
