higan v103r06

higan v103r06 is complied. higan (formerly bsnes) is a Nintendo multi-system emulator that began development on 2004-10-14. It currently supports the following systems:
- Famicom
- Super Famicom
- Game Boy
- Game Boy Color
- Game Boy Advance

higan also supports the following subsystems:
- Super Game Boy
- BS-X Satellaview
- Sufami Turbo

higan Changelog：
- processor/spc700: restored fetch/load/store/pull/push shorthand
functions
- processor/spc700: split functions that tested the algorithm used (`op
!= &SPC700:...`) to separate instructions
- mostly for code clarity over code size: it was awkward having
cycle counts change based on a function parameter
- processor/spc700: implemented Overload's new findings on which
cycles are truly internal (no bus reads)
- sfc/smp: TEST register emulation has been vastly improved¹

¹: it turns out that TEST.d4,d5 is the external clock divider (used
when accessing RAM through the DSP), and TEST.d6,d7 is the internal
clock divider (used when accessing IPLROM, IO registers, or during idle
cycles.)

The DSP (24576khz) feeds its clock / 12 through to the SMP (2048khz).
The clock divider setting further divides the clock by 2, 4, 8, or 16.
Since 8 and 16 are not cleanly divislbe by 12, the SMP cycle count
glitches out and seems to take 10 and 2 clocks instead of 8 or 16. This
can on real hardware either cause the SMP to run very slowly, or more
likely, crash the SMP completely until reset.

What's even stranger is the timers aren't affected by this. They still
clock by 2, 4, 8, or 16.

Note that technically I could divide my own clock counters by 24 and
reduce these to {1,2,5,10} and {1,2,4,8}, I instead chose to divide by
12 to better illustrate this hardware issue and better model that the
SMP clock runs at 2048khz and not 1024khz.

Further, note that things aren't 100% perfect yet. This seems to throw
off some tests, such as blargg's `test_timer_speed`. I can't tell how
far off I am because blargg's test tragically doesn't print out fail
values. But you can see the improvements in that higan is now passing
all of Revenant's tests that were obviously completely wrong before.
