MIPS64: Propagate DeoptInfo to cpu-profiler
Port 86cae1633caa31f2225b6932850fb13d3a21cf59
Original commit message:
1) Deoptimizer::Reason was replaced with Deoptimizer::DeoptInfo
because it also has raw position. Also the old name clashes with DeoptReason
enum.
2) c_entry_fp assignment call was added to EntryGenerator::Generate
So we can calculate sp and have a chance to record the stack for the
deopting
function.
btw it makes the test stable.
3) new kind of CodeEvents was added to cpu-profiler
4) GetDeoptInfo method was extracted from PrintDeoptLocation.
So it could be reused in cpu profiler.
