Implements LLVM based disassembler for the debugger. This will work for all of our platforms, x86, ARMv7, and AArch64. Main issue with this is that LLVM's cmake files aren't correctly finding the LLVM install. Not sure if this is Ubuntu's issue or not, it may just work on other operating systems. We could potentially improve this, you can pass in a specific CPU in to the LLVM disassembler. This would probably affect latency times that are reported by LLVM's disassembly? This needs to be further investigated later.

# This file only exists because LLVM's cmake files are broken.
# This affects both LLVM 3.4 and 3.5.
# Hopefully when they fix their cmake system we don't need this garbage.

Fixes LLVM library detection. I must have had a dirty cmake configuration which didn't encounter this issue. Make sure we are using LLVM_DEFINITIONS to know where we are linking to libraries at. Link against libLLVM-${VERSION}, the other one was linking us against static libraries...

Adds LLVM version check to cmake. We require LLVM 3.4 minimum, so if the user has something older make sure to not attempt compiling. Fixes issues #7858 and #7906.
