f178562ee7 a32_jitstate: Remove exception trap enables from FPSCR_MODE_MASK 
We don't currently use this for anything (we do not currently trap
floating point exceptions).

fdbafbc1ae x64/reg_alloc: Remove reference qualifier to variable in GetArgumentInfo()

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

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.

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.
