This imports the udis86 disassembler library. The library is placed
behind an abstraction in disassembler/Disassembler.h, so that we can
in the future use other disassemblers (for other platforms) whenever
appropriate. As a first step, the disassembler is being invoked for
DFG verbose dumps.
If we ever want to merge a new version of udis86 in the future, I've
made notes about changes I made to the library in
disassembler/udis86/differences.txt.
