da5dd3ff66 tests/A32/fuzz_arm: Remove unused Unix-specific include 
This was introduced within 6f6f60c61b,
however, the relevant code that it was used with has since been removed,
making the include unnecessary.

eadc07e269 a32_unicorn: Silence a truncation warning within UnmappedMemoryHook() 
MemoryRead8() takes a u32, but we were passing the result of a

u32 + size_t operation, which is 64-bit on 64-bit platforms. This
results in a truncation warning

7139942976 common: Move byte swapping functions to bit_utils.h 
These are quite general functions, so they can just be moved into common
instead of recreating a namespace here.

06b31448aa 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)

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.

f73104633b 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.

55eaa16615 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.
