a31194a877 Add some sanity checks when looking up syscalls. 
This may avoid crashing the emu when it starts executing junk (still not good of course, heh).

c7f1197ab1 Cut down on a debug check in release mode. 
In Jewel Summoner, for example, this gets called a lot, and eats a
measurable percentage of time.

dfbfed7534 Oops, avoid a crash on a bad HLE func. 
In the debug stats area.

732ae13ebb Fast path CallSyscall where possible. 
It seems we're spending a decent amount of time there, which isn't
entirely unexpected.  We can eliminate some things easily.

ee57498b16 Add a setting to skip 0xDEADBEEF reg filling. 
For debugging purposes.  Can't think of a better way.

9ebaf7b68b Fill registers with 0xDEADBEEF after most syscalls. 
Some, like sceMpegRingbufferPut(), we don't, since... it's complicated.
But most we do, like a real PSP does.

9311d405e9 Centralize and track imports/exports. 
So that we can "unresolve" them.

Also, correctly read delayslots using Read_Instruction on ARM.

b9c2e21105 Improve performance of syscall resolving. 
This was actually kinda slow (noticeably) in God Eater Burst.

0c41d4e952 Don't allow release wait for HLE delays. 
Although, presumably the thread would stop waiting, I guess the HLE func
in most cases probably checks and re-waits?

Fixes breakage in Jeanne d' Arc, which constantly releases from wait the
main thread, but calls things like sceMpegCreate which do block.

ba264b1df3 Don't delay results when dispatch is disabled. 
Wait won't work so the CoreTiming event will just cause havoc.

276037675f Prevent waiting on semas while dispatch disabled. 
Does relatively well on tests this way.

dba04a7e22 Add a function for HLE to consume cycles. 
Needed sometimes to make timing match better for tight loops.
Also removes the Puyo Puyo Fever hack.

015529cb49 Don't call time_update() when debug stats are off. 
This is not fast especially when syscalls are being hammered.

ce2ccd85b2 Fix misreporting of unknown syscalls. 
Unknown syscalls in known modules just weren't being reported.
Unknown syscalls in unknown modules were reported as Kernel_Library (which
is module 0.)

bcecd881b1 Savestate cleanup + be more careful with vectors. 
For some reason I debugged it going into std::string so I just made
them all more explicit which fixed everything.
