cd682e9e36 reset.c: Delete a comment suggesting a risky micro-optimisation 
reset_hard is not called that often, so it is not that important to
save cycles with an optimisation that could, as the comment seemed to
imply, cause a memory leak.

a22c424723 recomp.c: Remove Pure Interpreter checks 
This commit cleans up checks like the following in recomp.c:

  if (r4300emu != CORE_PURE_INTERPRETER && ...)

which became unreachable after the Pure Interpreter got its own opcode
dispatcher instead of forwarding everything to the Cached Interpreter.

851c130832 Decouple the Pure Interpreter from the Cached Interpreter 
This commit gives the Pure Interpreter its own opcode dispatcher. It
uses a switch statement to parse major and minor opcodes, then uses an
opcode's fields to kill writes to integer register 0, and gives whole
opcodes to interpreter functions for them to figure out what to do.

MFC0, MTC0, J, JAL, JALR, and the integer memory access instructions,
L* and S*, still used members of the Cached Interpreter's pre-parsed
instruction structure via 'PC->...'. They have been replaced with the
macros in macros.h (irt, rrd...), which the Pure Interpreter now uses
to parse opcode fields.

The new dispatcher decodes one opcode ahead only if the active opcode
is a jump with a delay slot. It also correctly handles killing jumps
that target themselves with a NOP (binary all-zeroes) in their delay
slots.

55166ef274 Isolate game_controller and rumblepak emulation from input plugin. 
This should allow for some flexibility in the choice of the controller
input and rumble output.
For now, we keep the old behavior and use the input plugin, but other
input source and rumble sink could be considered.
We hardcode te connection in the core, but ultimately,
the choice of an external controller/rumble should be the responsibilty
of the frontend.

8f7ee083ac Move AF_RTC time source out of SI subsystem. 
This should allow for some flexibility in the choice of a time source.
For now, we keep the old behavior and use the C localtime, but other
time source could be considered.
Furthermore, we hardcode the connection in the core, but ultimately,
the choice of an external time source should be the responsibility of
the frontend.
