10d691a277 JIT64: optimize some special cases of srawix 
Shift by 31 and 1, both of which are pretty common, can be done in a few less
instructions. Tested with a hwtest.

ee24d4714a JIT64: tweak srwx/slwx BindToRegister arguments 
Register B gets immediately moved into the shift register, so even if a == b
it doesn't need to be loaded.

608f9bcd67 Refactor opcode decoding a bit to kill FifoCommandRunnable. 
Separated out from my gpu-determinism branch by request.  It's not a big
commit; I just like to write long commit messages.

The main reason to kill it is hopefully a slight performance improvement
from avoiding the double switch (especially in single core mode);
however, this also improves cycle calculation, as described below.

- FifoCommandRunnable is removed; in its stead, Decode returns the
number of cycles (which only matters for "sync" GPU mode), or 0 if there
was not enough data, and is also responsible for unknown opcode alerts.

Decode and DecodeSemiNop are almost identical, so the latter is replaced
with a skipped_frame parameter to Decode.  Doesn't mean we can't improve
skipped_frame mode to do less work; if, at such a point, branching on it
has too much overhead (it certainly won't now), it can always be changed
to a template parameter.

- FifoCommandRunnable used a fixed, large cycle count for display lists,
regardless of the contents.  Presumably the actual hardware's processing
time is mostly the processing time of whatever commands are in the list,
and with this change InterpretDisplayList can just return the list's
cycle count to be added to the total.  (Since the calculation for this
is part of Decode, it didn't seem easy to split this change up.)

To facilitate this, Decode also gains an explicit 'end' parameter in
lieu of FifoCommandRunnable's call to GetVideoBufferEndPtr, which can
point to there or to the end of a display list (or elsewhere in
gpu-determinism, but that's another story).  Also, as a small
optimization, InterpretDisplayList now calls OpcodeDecoder_Run rather
than having its own Decode loop, to allow Decode to be inlined (haven't
checked whether this actually happens though).

skipped_frame mode still does not traverse display lists and uses the
old fake value of 45 cycles.  degasus has suggested that this hack is
not essential for performance and can be removed, but I want to separate
any potential performance impact of that from this commit.

494a60e41b VertexLoader: Change VtxDesc to use u64 instead of u32 
This is required to make packing consistent between compilers: with u32, MSVC
would not allocate a bitfield that spans two u32s (it would leave a "hole").
