Mitigate performance impact of respecting FP bit
...
In #135 we switched from a static OpcodeGrabber table to a
curOpcodeGrabber pointer in ppc_main_opcode. This results in an extra
indirection (as far as generated assembly having an additional load),
which reduces execution speed.
Switch to making the opcode grabber into a parameter to
ppc_main_opcode, and make ppc_exec_inner keep it up to date (via an
EXEF_OPCODE exception flag).
Also fixes FPU instructions in ppctests - we now need to set the FP
MSR bit when initializing the CPU.

Respect FP bit in MSR when running floating point instructions
...
Rather than running them normally, they should trigger a "no FPU"
exception. This appears to be required to allow correct graphical
rendering under Mac OS X - the FP bit cleared via mtmsr and rfi
instructions and something else appears to be relying on the exception
to be thrown.
Implemented by maintaining a parallel version of the OpcodeGrabber
table (OpcodeGrabberNoFPU) which contains alternate implementations
for all the floating point instructions. We switch the table whenever
the MSR value changes. This should minimize the overhead of doing
these checks.

nubusutils: rom_size fixes.
...
Support 64-bit file size.
Abort if file size > 16 MiB.
Calculate lane expanded memory size using integer arithmetic only.
Allocated memory is rounded to 4096 bytes. This can be adjusted. The lowest rounding of 4 would be "+ 3) / 4 * 4" instead of "+ 4095) / 4096 * 4096".
Abort if ROM size after lane expansion is > 16 MiB.
Expand lanes starting with the last byte instead of the first since the last byte must align with the last used lane of the memory range.
Include ROM image name in exceptions.
