Don't recurse when disasming an emuhack.

The order makes more logical sense from game disassembly, and matches the

Don't zero out downcount in replacements.

It doesn't write out js.downcountAmount in any of these cases, so zeroing
it is wrong.

Disable a bunch of function replacements.

These are just for speed, let's turn them off. Using a flag because:
* I think there's still some issue with savestates, not sure.
* We might swap this flag to a separate option.

Limit stack walk distance a bit.

It was spending 0.5s in debug scanning all of memory for an entry (due to
some fp/sp tricks that aren't well detected yet.) Let's just assume a 1MB
func doesn't need to be walked properly.

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.
