fdbafbc1ae x64/reg_alloc: Remove reference qualifier to variable in GetArgumentInfo() 
The result of GetArg() is returned by value, so this is essentially
still a copy. While the previous code *is* valid, this communicates what
is actually happening a little more explicitly.

1f6878fb46 ir_opt/verification_pass: Add include for std::puts 
Ensures that the header dependency is always satisfied directly, and not
through other project headers. While we're at it, we can qualify the
call with the std:: namespace.

fc9c59d056 ir_opt/verification_pass: Eliminate redundant GetArg() 
Given the same argument is used inside the condition's body if it's
true, we can just utilize the local to cut out a GetArg() operation.
Avoids redundant internal assertion checking.

92daae9513 A32/coprocessor: Remove boost from public interface 
Removes a boost header from the public includes in favor of using the
standard-provided std::variant.

The use of boost in public interfaces is often a dealbreaker for some
people. Given we use std::optional in the header already, we can
transition over to std::variant from boost::variant.

With this removal, this makes all of our dependencies internal to the
library itself.

e37689315d A32: Implement ARM-mode CRC32 instructions 
Implements the ARM-mode variants of the CRC32 instructions introduced
within ARMv8. This is also one of the instruction cases where there is
UNPREDICTABLE behavior that is constrained (we must do one of the
options indicated by the reference manual).

In both documented cases of constrained unpredictable behavior, we treat
the instructions as unpredictable in order to allow library users to
hook the unpredictable exception to provide the intended behavior they
desire.

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.

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.

LDNP and STNP indicate that a memory access is non-temporal/streaming

performed. However, given this is only a hint, we can treat these two
instructions as regular LDP and STP instructions for the time being.

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.

e739624296 ir: Add opcodes for vector CLZ operations 
We can optimize these cases further for with the use of a fair bit of
shuffling via pshufb and the use of masks, but given the uncommon use 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.
