97277c598b A32: Rename vfp2-related files to vfp 
Now that we fuzz against Unicorn, we aren't just restricted to VFPv2.
VFPv3 and VFPv4 facilities can now be implemented. This renames
constructs mentioning VFPv2 to just refer to VFP.

966e04d03d A32: Allow hooking of hint instructions in ARM mode. 
Mirrors the hooking functionality from the AArch64 frontend to make the
behavior of both consistent.

e37689315d A32: Implement ARM-mode CRC32 instructions 
Implements the ARM-mode variants of the CRC32 instructions introduced
within ARMv8. This is also one of the instruction cases where there is
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.

f01dc9192a CMakeLists: Add a namespace to the export 
Avoids potentially dumping boost, fmt, and xbyak targets into a
top-level namespace without any qualification, which can lead to build
errors in projects that already make use of them.

8103652a91 frontend: Move imm.h to the top-level directory of the frontends 
Preparation to utilize the immediate type within the A32 backend as
well, which will allow eliminating numerous type aliases like Imm4,
Imm5, etc.

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.

b2f7a0e7ba A32: Implement ARM-mode SDIV/UDIV 
Now that we have Unicorn in place, we can freely implement instructions
introduced in newer versions of the ARM architecture.

bfaeb08d3c A64: Implement LDNP/STNP 
LDNP and STNP indicate that a memory access is non-temporal/streaming
(i.e. unlikely to be repeated), allowing data caching to not be
performed. However, given this is only a hint, we can treat these two
instructions as regular LDP and STP instructions for the time being.

3290a9fdc2 common: Remove address_range.h 
The AddressRange structure isn't used anywhere within the codebase, so
this can be removed. Particularly because there's no real appeal/heavy
potential use of it in the future that isn't trivial to add back if
needed.
