b03460c169 Improve function range detection. 
This improves a pattern like this:

  j endOfLoop;
  li v0, 0;
  startOfLoop:
  addiu v0, v0, 1
endOfLoop:
  bne v0, a0, startOfLoop;
  nop
  jr ra
  nop

Where it jumps to the end of the loop, which only jumps back to the top of
the loop.  This might misdetect a few cases of tail recursion, but only
when the funcs are right next to each other.

Also, stops scanning at a jr ra, which was causing funcs to be incorrectly
long in cases.

a59d8b5c1f Override the codehashing func used in Peace Walker. 
This makes the demo work fine even with jit enabled.  May help the full
game when fighting a certain boss.

81096f6bd0 Hook Dissidia's avi record func. 
This makes it so replays can be recorded.  Though you could probably just
record separately anyway.

0da972c548 Hook the FF1 battle effect func. 
So that we can download the framebuffer.  At least, it seems like that's
what this function is doing.

ec94498342 When scanning or relocating, check replacements. 
Just to make sure we don't wrongly detect the length or unresolve a var
wrong etc.

0550b9372a Skip nop padding between functions.

memcpy.

a926b19c03 Hook Tales of Phantasia X save pictures. 
Maybe other games will use the same func even.  This makes save pictures
work correctly the first time.

a7b9ce205b Enable function replacements by default. 
So things like Star Ocean work, and game memcpy()'s to GPU work.

This will make game start on mobile a bit slower, though.  And there could
still be bugs so leaving as an option, but seems pretty stable.  Didn't
realize it wasn't enabled by default.

b2dc92b942 Add a hook for Hexyz Force's "monoclome" thread. 
This fixes missing graphics in some areas in GLES, due to direct framebuf
access.

f489694515 Add the option to hook, rather than replace, funcs. 
This can be useful for debugging or developing translations/game hacks,
and also gives us options when dealing with GLES incompatibilities.

around.

dde2f3ade6 Re-replace functions after loading a savestate. 
Might need to clear before saving too... anyway, this makes testing a bit
easier for certain areas.

Also, correctly decrease downcount on x86.

8948990871 Optimize searching for existing symbols. 
Checking every time is slow, we should just skip by the address.  Some is
just the locking overhead.

7c2d36e802 Don't add to the symbol map what was found there.

b1d6eefb8a Call UpdateActiveSymbols only once from MIPSAnalyst instead of for every recognized function. 
Reduces startup slowdown when using a function signature file drastically.

fe2b62c27d Make the "on change" checkbox for memchecks work. 
But, for now, only on sw and similar instructions, the rest don't work
yet and just always break.

76afb2a8d5 Avoid returning points from the symbol map. 
Now that it uses a lookup, this is even more dangerous.  But, the maps
could be reordered while it's trying to print the pointer and cause that
data to become invalid.

This should be safe from race conditions.

2140892074 Initial preparations for ability to replace game functions with custom implementations. 
Also auto-saves hashmap additions and reapplies the hashmap on function
rename so that if you rename a function that exists in several copies
they will all be labelled.

Note that actual function replacement is not activated yet.
