59dc33ef12 emit_x64_vector: Changes to VectorSignedSaturatedDoublingMultiply 
* Return both the upper and lower parts of the multiply if required
* SSE2 does not support the pmuldq instruction, do sign correction to an unsigned result instead
* Improve port utilisation where possible (punpck instructions were a bottleneck)

02357939ac 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.

72ed55f143 a32_emit_x64: Fix incorrect BMI2 implementation for SetCpsr 
* The MSB for each byte in cpsr_ge were not being appropriately set.
* We also expand test coverage to test this case.
* We fix the disassembly of the MSR (imm) and MSR (reg) instructions as well.

fc6b73bd85 a64_emit_x64: Ensure host has updated ticks in EmitA64GetCNTPCT 
Discovered by @Subv.
Fixes incomplete fix begun in 5a91c94dca47c9702dee20fbd5ae1f4c07eef9df.
That fix fails to take into account that LinkBlock doesn't update ticks until there
are no remaining ticks to be executed.

Test added to confirm fix.

a665470545 fuzz_with_unicorn: Move std::vector outside loop in small random block test case 
Avoids constructing and destructing the vector repeatedly, we can just
alter the contents of the vector on each iteration instead. Also move
out the std::array instances as well, like with the floating-point test
case and the single random instruction test case.

We can also use the regular form of std::generate and avoid hardcoding
size values twice.
