Convert the A32 coprocessor instructions to decodetree. Note that this corrects an underdecoding: for the 64-bit access case (MRRC/MCRR) we did not check that bits [24:21] were 0b0010, so we would incorrectly treat LDC/STC as MRRC/MCRR rather than UNDEFing them. The decodetree versions of these insns assume the coprocessor is in the range 0..7 or 14..15. This is architecturally sensible (as per the comments) and OK in practice for QEMU because the only uses of the ARMCPRegInfo infrastructure we have that aren't for coprocessors 14 or 15 are the pxa2xx use of coprocessor 6. We add an assertion to the define_one_arm_cp_reg_with_opaque() function to catch any accidental future attempts to use it to define coprocessor registers for invalid coprocessors.

Unicorn Engine
Unicorn is a lightweight, multi-platform, multi-architecture CPU emulator framework based on QEMU.
Unicorn offers some unparalleled features:
- Multi-architecture: ARM, ARM64 (ARMv8), M68K, MIPS, SPARC, and X86 (16, 32, 64-bit)
- Clean/simple/lightweight/intuitive architecture-neutral API
- Implemented in pure C language, with bindings for Crystal, Clojure, Visual Basic, Perl, Rust, Ruby, Python, Java, .NET, Go, Delphi/Free Pascal and Haskell.
- Native support for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed)
- High performance via Just-In-Time compilation
- Support for fine-grained instrumentation at various levels
- Thread-safety by design
- Distributed under free software license GPLv2
