Mitch Phillips	2471073a0b	Update cl::opt<uint64_t> instances to cl::opt<unsigned long long> ... cl::opt<uint64_t> fails when parsing command line arguments. See https://bugs.llvm.org/show_bug.cgi?id=19665.

Mitch Phillips	b2fffdec52	Parse DWARF information to reduce false positives. ... Summary: Help differentiate code and data by parsing DWARF information. This will reduce false positive rates where data is placed in executable sections and is mistakenly parsed as code, resulting in an inflation in the number of indirect CF instructions (and hence an inflation of the number of unprotected). Also prints the DWARF line data around the region of each indirect CF instruction.

Mitch Phillips	fa601dee99	Graph builder implementation. ... Implement a localised graph builder for indirect control flow instructions. Main interface is through GraphBuilder::buildFlowGraph, which will build a flow graph around an indirect CF instruction. Various modifications to FileVerifier are also made to const-expose some members needed for machine code analysis done by the graph builder.
