The 68LC040 generates a format 4 stack frame for floating point
...
exceptions, which puts the address of the instruction we faulted
on in a different location. Copy it and handle as we normally would,
restoring the saved PC before returning.
The FPE should probably be reworked to take advantage of the 68LC040's
precalculated effective address, at some point.

Fix FMOVEM emulation; postincrement modes use different ordering than

predecrement modes, per 68K Programmer's Manual p. 5-88. Pointed out
by Takeshi Nakayama <takeshi@sakabe.nuie.nagoya-u.ac.jp>, verified by me.

Still incomplete, but much more complete FPE from Ken Nakata
...
<kenn@remus.rutgers.edu>. This emulator does not yet emulate
the following functions:
FSINH, FETOXM1, FTANH, FATAN, FASIN, FATANH, FSIN, FTAN,
FETOX, FTWOTOX, FTENTOX, FCOSH, FACOS, FCOS, FSINCOS
It is sufficient, however, to allow programs like df, w, and newfs,
to run to completion with correct results.
Portions of this code were based on the sparc fpe and on initial
work by gwr.
