7752ffc50c a64_emit_x64: Convert std::vector instances in GenFastmemFallbacks() to std::array 
Given these are quite small, we can avoid the need to heap allocate

07c197e8d0 constant_propagation_pass: Add 64-bit variants of shifts to the pass 
These optimizations can also apply to the 64-bit variants of the shift
opcodes; we just need to check if the instruction has an associated
pseudo-op before performing the 32-bit variant's specifics.

While we're at it, we can also relocate the code to its own function
like the rest of the cases to keep organization consistent.

8248999c5d constant_propagation_pass: Fold division operations where applicable 
We can fold division operations if:

1. The divisor is zero, then we can replace the result with zero (as this is how
ARM platforms expect it).
2. Both values are known, in which case we can just do the operation and
store the result
3. The divisor is 1, in which case just return the other operand.

7ad6981437 constant_propagation_pass: deduplicate common 32/64 bit checking for results in folding functions 
It's common for an folding operation to apply to both the 32-bit and
64-bit variant of the same opcode, which leads to checking which kind of
result we need to store the value as. This moves it to its own function,
so that we don't need to duplicate it in various functions.

72daf37208 constant_propagation_pass: Fold Mul32 and Mul64 cases where applicable 
Multiplication operations can currently be folded if:

1. Both arguments are known constant values
2. Either operand is zero (in which case the result is also zero)
3. Either operand is one (in which case the result is the non-one
operand).

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.

e739624296 ir: Add opcodes for vector CLZ operations

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.
