819d475181 poweropcodes: fix div emulation.
Clean up power_doz and power_maskir as well.

1b4de3b64e Fix emulation of doz, dozi, and nabs POWER instructions
doz and dozi were storing the result into the wrong register.

nabs was not taking into account two's complement storage of numbers
and was just setting the signed bit.

These two instructions are used in the implementation of text
measurement in native QuickDraw on 7.1.2/the PDM ROM, and the incorrect
values were resulting in nothing being rendered. With the fix text
appears when booting from the 7.1.2 CD.

35c86ad6bf Clean up #includes
Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.

Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.

64fec88436 Fix compiler warnings: cast loses precision.
Use explicit cast when converting large integer types to smaller integer types when it is known that the most significant bytes are not required.
For pcidevice, check the ROM file size before casting to int. We'll allow expansion ROM sizes up to 4MB but usually they are 64K, sometimes 128K, rarely 256K.
for machinefactory, change the type to size_t so that it can correctly get the size of files that are larger than 4GB; it already checks the file size is 4MB before we need to cast to uint32_t.
For floppyimg, check the image size before casting to int. For raw images, only allow files up to 2MB. For DiskCopy42 images, it already checks the file size, so do the cast after that.

983e278498 Refactoring 601 opcode emulation - part 1
All opcodes should be emulated now. There was also a significant amount of clean-up, particularly with lscbx and the bit rotation/shifting instructions.
