134b586c5c frontend/ir/ir_emitter: Amend arguments to conversion opcodes 
Accidentally caused within 967d1fcc8d6f60749a162a96b997439450fed687.
That one's on me. My bad.

e4c65721fe frontend/ir/type: Generify std::array declaration 
With deduction guides, we can eliminate the need to explicitly size the
array. Also newlines the elements based off their relation, making it
slightly nicer to read.

0a35836998 frontend/ir/ir_emitter: Use switch constructs in floating point opcodes where applicable 
This'll reduce the amount of noise necessary in changes implementing
half-precision instructions, as the type can just be prepended to the
switch cases, instead of rewriting the whole if/else branch.

8316d231e9 A32: Implement barrier instructions introduced in ARMv7 
Provides basic implementations of the barrier instruction introduced
within ARMv7. Currently these simply mirror the behavior of the AArch64
equivalents.

06ec6ab0da frontend/ir/cond: Remove unused invert() function 
This is no longer used by anything in the codebase, so it can be

4fc531f71b ir/basic_block: Forward declare headers where applicable 
Now that the constructor and destructors have been placed within the cpp
file, we can forward declare the memory pool data structures. Now, a
change to the memory pool code won't ripple across the entirety of the
IR emitter.

9309d95b17 ir/block: Default ctor and dtor in the cpp file

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.

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.
