10abc77fad A64: Handle half-precision floating point in scalar FNEG
With the half-precision variant of the FPNeg opcode added, we can
utilize it here to emulate the half-precision variant of FNEG.

25a7256ee1 A64: Enable FMOV (general) for half-precision floating point
This just transfers values between vector registers and general-purpose
registers with no conversions performed, so this is trivial to add
support for half-precision to.

instructions as regular LDP and STP instructions for the time being.

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

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
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.

134bb02e19 ir/value: Replace includes with forward declarations
enum classes are still considered complete types when forward declared
(as the compiler knows the exact size of the type from the declaration
alone). The only difference in this case being that the members of the
enum class aren't visible. Given we don't use the members within this
header in any way, we can simply forward declare them here and remove
the inclusions.

Now that the vector rotation helpers are in, replace the explicit
shifting with the relevant helper function that does the same thing.

Simply tidies up code; no behavioral changes are made.
