09d3c77d74 IR: Add masked shift IR instructions 
Also use these in the A64 frontend to avoid the need to mask the shift amount.

af3614553b A64/impl: Move AccType and MemOp enum into general IR emitter header 
These will be used by both frontends in the future, so this performs the
migratory changes separate from the changes that will make use of them.

349d4b577a General: Remove unnecessary includes 
Removes unnecessary header dependencies that have accumulated over time
as changes have been made. Lessens the amount of files that need to be
rebuilt when the headers change.

182ceb2807 General: Make parameter names from declarations and implementations consistent 
Most of the time when this occurs, it's a bug. Thankfully this isn't the
case. However, we can resolve these cases to make the codebase more
consistent.

95d9baea67 {A32, A64}/types: Use std::array deduction guides where applicable 
We also make the arrays static here, as MSVC tends to load the whole
array every time the function is called, instead of storing the data
within rodata.

This also line breaks the elements a little earlier for readability.

8103652a91 frontend: Move imm.h to the top-level directory of the frontends

Imm5, etc.

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.
