ed0aa5928f Gekko: Remove unused UReg_PTE 
PTEs are only ever operated on in terms of their halves in our code
currently, so this can be removed.

029aff0741 MMU: Remove now-unused defines 
Now that we're using register unions where applicable, we can remove
these defines, since they're now unused.

7a6b63b309 MMU: Don't truncate 64-bit values when calling Memcheck() 
Previously in Read_U64 and Write_U64 the value that was read or written
would be truncated to a 32-bit value before being passed off to the
memcheck handler, which can result in incorrect values being logged out.

75840f62ff MMU: Make use of UReg_SDR1 in SDRUpdated() 
Lets us simplify SDRUpdated() a little bit.

This also fixes the layout of UReg_SDR1. Turns out this struct has been
incorrect (from a little-endian perspective) the entire time and went
unnoticed, since the union was never used.

3216040bfe MMU: Remove implicit sign conversions and truncation in UpdateTLBEntry 
These are trivial to resolve.

Converting the structure member into a u32 results in no increase in
structure size, as it's making use of the three extra padding bits in
the structure.

change.

f70ddebb40 JitArm64: Disable indexed paired loadstore instructions 
Since the merge of b24b79e, we've gotten reports that the
following games are broken on JitArm64:

* Sonic Heroes
* The SpongeBob SquarePants Movie
* Astérix & Obélix XXL
* The Incredibles: Rise of the Underminer

Disabling the register cache avoids the issue, so the cause
of the bug might not actually have anything to do with the
newly implemented instructions. Nevertheless, I don't want
to ship a beta with this problem present, so I would like to
disable these instructions for the time being.

0cf8405126 JitArm64: Make HandleFastmemFault less unsafe 
HandleFastmemFault works correctly when faults only happen in
expected locations, but it does some things that are rather
dangerous for faults in unexpected locations, like decrementing
an iterator without checking whether it's equal to begin.

This change cleans up the logic by making m_fault_to_handler's
key be the end of the fastmem region instead of the start.

90fcaf7e96 Jit: Use one less register in dcbx 
We were using a "value" register to avoid clobbering physical_addr,
but this isn't actually needed anymore. The only bits we need from
physical_addr after we start clobbering it are bits 5-9, and
those bits are identical in effective_addr and physical_addr,
so we can read them from effective_addr instead.

b7b45eb111 Interpreter: Make signedness and narrowing conversions explicit 
Makes our conversions between the different signs explicit to indicate
that they're intentional and also silences compiler warnings when
compiling with sign conversion or stricter truncation warnings enabled.

62e7b34c88 JitArm64: Don't lock W30 in dcbx 
If W30 is in use and we don't lock it, it will be pushed to the
stack before the BLR, so there isn't really any reason to lock W30.
