c324983340 Make the jit support bltzal and friends.
Fixes problems with jit in games.  Android changes completely untested.

de2df87758 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.

a9d0390426 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.

d99d060c2e Decrement downcount in skipped likely slots.
Pretty sure this is right, it eats up a cycle as a nop.

Also some funny indentation.

8438371941 Read memory in the jit dispatcher same as lw.
Just for consistency.  One less op, maybe faster, probably same.

4c271fc09e Add DELAYSLOT and LIKELU flags to some ops.
Should improve cycle estimate, and makes analysis easier.

e8dc99328a Avoid using EAX as a temporary where possible.
All the regs should be indirect addressing compatible.  So if it's
in a reg, let's use that instead of EAX.

385417effe Log jit misses at runtime instead of compile time.
Really, it could be very different after all... this shouldn't be
all that slow, I guess.

d5ae85201c Optimize sw/lw even under safe memory.
They're very common instructions, so shaving cycles helps.

beac991a9e Clear jit cache when changing breakpoints.
For now, only when paused.  I don't think clearing the cache while
running is an awesome idea.

a9293c8923 Add breakpoints to x86 jit for easier debugging.
They should be really fast so leaving them on in release.

74cce1439b Allow downcount to be negative.
This fixes threads/alarm/alarm and ctrl/sampling2/sampling2, which were
broken in 674911dd.

The downcount can go negative for a few reasons, and was signed before.
