Sintendo b0be20560f Jit64: subfx - Special case b == 0
Happens in Super Mario Sunshine. You could probably do something similar
for b == -1 (like we do for subfic), but I couldn't find any titles that
do this.

- Case 1: d == a

Before:
41 8B C7             mov         eax,r15d
41 BF 00 00 00 00    mov         r15d,0
44 2B F8             sub         r15d,eax

After:
41 F7 DF             neg         r15d

- Case 2: d != a

Before:
BF 00 00 00 00       mov         edi,0
41 2B FD             sub         edi,r13d

After:
41 8B FD             mov         edi,r13d
F7 DF                neg         edi

Sintendo b805223108 Jit64: subfx - Optimize more constant a cases
Consider the case where d and a refer to the same PowerPC register,
which is known to hold an immediate value by the RegCache. We place a
ReadWrite constraint on this register and bind it to an x86 register.
The RegCache then allocates a new register, initializes it with the
immediate, and returns a RCX64Reg for both d and a.

At this point information about the immediate value becomes unreachable.
In the case of subfx, this generates suboptimal code:

Before 1:
BF 1E 00 00 00       mov         edi,1Eh       <- done by RegCache
8B C7                mov         eax,edi
8B FE                mov         edi,esi
2B F8                sub         edi,eax

Before 2:
BE 00 AC 3F 80       mov         esi,803FAC00h <- done by RegCache
8B C6                mov         eax,esi
8B 75 EC             mov         esi,dword ptr [rbp-14h]
2B F0                sub         esi,eax

The solution is to explicitly handle the constant a case before having
the RegCache allocate registers for us.

After 1:
8D 7E E2             lea         edi,[rsi-1Eh]

After 2:
8B 75 EC             mov         esi,dword ptr [rbp-14h]
81 EE 00 AC 3F 80    sub         esi,803FAC00h

Pokechu22 e825af7b1b Software: Remove normalization special case
The special case doesn't appear to make a significant difference in any games, and the current implementation has a (minor, fixable) issue that breaks Super Mario Sunshine (both with a failed assertion (https://bugs.dolphin-emu.org/issues/11742) and a rendering issue (https://bugs.dolphin-emu.org/issues/7476)).  Hardware testing wasn't able to reproduce the special case, either, so it may just not exist.

PR #9315 contains a fixed implementation of the special case on all video backends, and can serve as a basis for it being reintroduced if it is found to exist under more specific circumstances.  For now, I don't see a reason to keep it present.

Filippo Tarpini 1e4a1bee43 Fix DualShockUDP not adding/removing devices correctly
-If adding 2 devices with the same name, they their unique id wouldn't be increased, causing a conflict.
-Removing a device wouldn't actually remove it from the internal devices list because the list of devices had already been updated when going through it.
-It was possible to remove devices belonging to other sources by adding a device with the same name and then removing it.

Filippo Tarpini 57c59c18d4
Rename "Use Fullscreen" setting to "Start in Fullscreen"
The name was confusing as changing it at runtime would not change the window to fullscreen, as it effectively only affects the start of the emulation.
Also blocked the ability to change it when the emulation is running, to be more inline with other similar settings, like "Render to main Window".
