Read memory in the jit dispatcher same as lw.

Just for consistency.  One less op, maybe faster, probably same.
Decrement downcount in skipped likely slots.

Pretty sure this is right, it eats up a cycle as a nop.

Also some funny indentation.
Show the current tick count in the disasm dialog.

Might as well show something under Ctr:...
Don't over decr downcount when hitting a jit bp.
A branch was missing inDelaySlot, refactor it.
Fix headless segfault on win32.
Adjust downcount before syscalls, not after.

This makes jit slightly slower for syscalls, but it's minor and makes
sure jit and interpreter timing are determistically the same.
Make interpreter call Advance() the same as jit.

Probably makes more sense anyway, since the first events will be
more correctly timed, like savestates, sound, etc.
