b5bf890584 load_store_*: Make bracing consistent and variables const where applicable
Makes bracing consistent, and variables const where applicable to be
consistent with the rest of the codebase.

In most bracing cases, they'd need to be added to conditionals that
would involve checking stack pointer alignment in the future anyways.

7bb5440507 general: Mark hash functions as noexcept
Generally hash functions shouldn't throw exceptions. It's also a
requirement for the standard library-provided hash functions to not
throw exceptions.

An exception to this rule is made for user-defined specializations,
however we can just be consistent with the standard library on this to
allow it to play nicer with it.

While we're at it, we can also make the std::less specializations
noexcpet as well, since they also can't throw.

64de80839e A64/impl: Reorganize peculiar void use in V_scalar
To a reader this might look particularly strange, given the function
itself has a void return value, but this is actually valid, given the
function in the return statement also has a void return value.

This instead alters it to be a little easier to parse and potentially be
a little less confusing at a glance.

Lioncash
8309d49588 A64: Handle reserved instruction cases more specifically where applicable
These are cases that are defined as reserved within the ARMv8 reference
manual, so we can handle them as such instead of as unallocated
encodings.

While this doesn't actually change emulated behavior, it does at least
allow the JIT to generate the more appropriate exception.

7bc7042104 simd_scalar_shift_by_immediate: Change UnallocatedEncoding() path in SaturatingShiftLeft to ReservedValue()
Strictly speaking, immh being zero is defined as reserved in the ARMv8

SQSHL immediate scalar variant.

4a3c064b15 ir/value: Add an IsZero() member function to Value's interface
By far, one of the most common things to check for is whether or not a
value is zero, as it typically allows folding away unnecesary
operations (other close contenders that can help with eliding operations  are 1 and -1).

So instead of requiring a check for an immediate and then actually
retrieving the integral value and checking it, we can wrap it within a
function to make it more convenient.

d69fceec55 value: Move ImmediateToU64() to be a part of Value's interface
This'll make it slightly nicer to do basic constant folding for 32-bit
and 64-bit variants of the same IR opcode type. By that, I mean it's
possible to inspect immediate values without a bunch of conditional
checks beforehand to verify that it's possible to call GetU32() or
GetU64, etc.

f40fcda1f6 ir/value: Add member function to check whether or not all bits of a contained value are set
This is useful when we wish to know if a contained value is something
like 0xFFFFFFFF, as this helps perform constant folding. For example the
operation: x & 0xFFFFFFFF can be folded to just x in the 32-bit case.

We can optimize these cases further for with the use of a fair bit of

this instruction, I wouldn't consider it to be beneficial in terms of
amount of code to be worth it over a simple manageable naive solution
like this.

If we ever do hit a case where vectorized CLZ happens to be a
bottleneck, then we can revisit this. At least with AVX-512CD, this can
be done with a single instruction for the 32-bit word case.
