85ff068e20 Fix sleigh for fint/fintrz 
Without additional machinery, fint can't be precisely modeled because the rounding mode is controlled by the state.  fintrz always rounds to zero.  I think whoever implemented fint probably meant to implement fintrz.

058fa90387 Issue 4807 Fix movem PC instruction bug on 68000 
The `movem` instruction's `(d16, PC)` addressing mode has an instruction
word, a mask word, and then an extension word. The addressing mode
uses the value of PC incremented to the extension word, in this case
`instr_start + 4`. The sleigh code incorrectly uses `instr_start + 2`.
The issue is present for both `movem.w` and `movem.l` variants. This
PR fixes the `PC` offset to `+4`.

See 68000 reference manual page 2-13 for PC indirect addressing mode,
and 4-128 for MOVEM documentation.

Partially addresses #4807.

b1c54e36e1 Fix pea SP instruction bug on 68000 processor 
The `pea` instruction adjusts `SP`, but the address may be `SP`-based.
Ghidra was evaluating the effective address after adjusting `SP`, but
the address should be evaluated before `SP` is changed. For example,
`pea (SP)` should result in a pointer to the previous stack entry,
rather than a pointer to itself.
