7c6844e895 ES/Formats: Work around a GCC bug
In old GCC versions, capturing 'this' does not work for some lambdas.
The workaround is to not use auto for the parameter (even though the
type is obvious). This can be dropped once we require GCC 7.

155bcb1649 Interpreter_FloatingPoint: Set FPSCR.VXSNAN if the input to frsqrte is a signaling NaN
If the input is a signaling NaN, then we need to signal that via setting
the FPSCR.VXSNAN bit. We also shouldn't update the FPRF flags if
FPSCR.VE is set.

31504f85a7 Interpreter_FloatingPoint: Don't update FPRF in frsqrte in certain exceptional cases
If the FPSCR.VE bit is set and an invalid operand is passed in, then the FPRF
shouldn't be updated. Similarly this is also the case when the FPSCR.ZE bit
is set and negative or positive zero is passed in as the operand.

34adc529a7 Interpreter_FloatingPoint: Don't update the FPRF in fres in certain exceptional cases
If FPSCR.ZE is set and a divide by zero exception is signaled, then the
FPRF shouldn't be updated with a result. Similarly, if the input is an
SNaN and FPSCR.VE is set, then the FPRF shouldn't be updated.

dfea5cb00d Interpreter_FPUtils: Set the FPSCR.VX bit if any invalid operation exception bits are set
The VX bit is intended to be a summary bit indicating the occurrence of
any kind of invalid operation. Therefore, whenever an invalid operation
exception is set, also set VX.

This corrects our CR flag setting for multiple instructions in certain
scenarios. This corrects flag setting cases in fadd, fadds, fctiw, fctiwz, fdiv,
frsp, frsqrte, fsub, and fsubs (and technically every floating-point
instruction that we make more accurate in the future with regards to
flag setting).

Port FS, SD and dump path to onion config

c99ac40700 Port FS, SD and dump path to onion config
This ports the Wii filesystem root, Wii SD card path and dump path
settings to the new config system (OnionConfig).

My initial plan was to wait until DolphinWX was removed before porting
most of the Main (Core, DSP, General) settings to onion config, but
I've decided to submit a small part of those changes to fix
[issue 10566](https://bugs.dolphin-emu.org/issues/10566).

Removes the need to manually set the FileUtil path in the UI frontends
and gets rid of some more members that don't really belong in SConfig.

Also fixes a bug which would cause the dump path not to get created
after change.

593f58be6c Move Wii FS content init to happen after Boot
Initialising Wii filesystem contents should be done after Boot and
not in HW to ensure that we operate with the correct title context
and to make sure required title directories exist (so that Movie and
Netplay code can copy data from and to the temporary NAND).

9a088e008f Interpreter: Check processor privilege level when executing supervisor instructions
Executing a supervisor-level instruction in user mode is supposed to
cause a program exception to occur.

The following supervisor instructions are present:

- dcbi
- mfmsr
- mfspr
- mfsr
- mfsrin
- mtmsr
- mtspr
- mtsr
- mtsrin
- rfi
- tlbie
- tlbsync

In 0337ca116abe9b9b9877e6071ad0697188198885 checks within mfspr and
mtspr were added. This change adds the trivial checks to the other
instructions.

edb38ff144 MMU: Avoid sign conversions in EFB_Read and EFB_Write
There's no reason to use int here as opposed to an unsigned value.
Video_AccessEFB() takes its arguments as u32 values, so we'd be doing
sign conversions for no reason here (along with causing avoidable
compiler warnings).

0337ca116a Interpreter_SystemRegisters: Check processor privilege level in mfspr and mtspr
If a program executing in user mode tries to write to any SPRs other than
XER, LR, or CTR registers, then a program exception occurs. Similarly
this also applies for reading SPRs as well, however the upper and lower
timebase halves can also be read (but not written to).

355b1b5d5b ec: Improve readability and clarity
- Move all of the ec functions into the Common::ec namespace.

- Give the public functions better names and some usage information.

- Move all of the "elt" related functions into an "elt" class including
  all of the arithmetic operations, so that the logic becomes clearer
  and feels less like assembly.

  This also makes it much more obvious what the parameters are, instead
  of only using unsigned char* (which doesn't tell anything about what
  the pointer is used for or the size).

- Similarly, add a new "Point" class and move point functions there.
  Overload the arithmetic operators to make calculations easier to read

9ad7d9ff87 Jit64/JitArm64: Remove unnecessary code buffer parameter for DoJit()
This function in both JITs is only ever called by passing the JIT's code
buffer into it. Given this is already accessible, since the functions
are part of the respective JIT class, we can just remove this parameter.
This also cleans up accesses with the new code buffer, as we don't need
to do janky looking dereference-then-index expressions.

3a8a67025e PPCAnalyst: Make CodeBuffer an alias for std::vector<CodeOp>
This class effectively acted as a "discount vector", that would simply

We can just use a std::vector directly to reduce this boilerplate.
