As discussed in bug 278417, some ports require the F16C instruction set
to compile, but there is no way yet to detect whether the currently
chosen CPUTYPE supports this feature.

Add the feature to the MACHINE_CPU variable, for each processor that
supports it. The list of processors was extracted from clang 18's -dM
output, filtered on the __F16C__ define.

MACHINE_ABI is a list of properties of the ABI used for MACHINE_ARCH.
It should be used in place of long conditionals on MACHINE_ARCH where

The following properties are indicated with one of the follow values:

Byte order: big-endian, little-endian
Floating point ABI: soft-float, hard-float
Size of long (size_t, etc): long32, long64
Pointer type: ptr32, ptr64
Size of time_t: time32, time64

For example, i386 targets will be:
