Log:
[profile] Add CFG view to profile page.
This implements the mockup presented on slide 32 of
http://llvm.org/devmtg/2015-10/slides/Beyls-AutomatedPerformanceTrackingOfLlvmGeneratedCode.pdf
The control flow graph is constructed by scanning instruction
disassembly, looking for instructions that change control flow. This is
done by matching instruction text with regular expressions. This isn't
perfect, but can reconstruct CFGs well in most cases. Furthermore, for
this visualization tool, it isn't required that the CFG will always be
reconstructed 100% correctly.
This patch only implements regular expressions to reconstruct the
Control Flow Graph for the AArch64 instruction set. It doesn't implement
all necessary regular expressions for AArch64. Nonetheless, the CFG is
already reconstructed well in surprisingly many cases.
