Lioncash 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.

Lioncash 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.

Lioncash fe95575b95 general: Replace unreachable-imitating assertions with UNREACHABLE() 
We can just use the self-documenting assertion for indicating
unreachable paths, instead of manually passing false and providing a
message.

Lioncash 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.
