jit: Implement support for perf dump
Using perf dump is superior to using perf map as we are
able to use `perf annotate` which means we can view which
x86 assembly instruction was using the most CPU.
perf record -k mono erl +JPperf true
perf inject --jit -i perf.data -o perf.jitted.data
perf report -M intel -i perf.jitted.data
The implementation was inspired from the mono repo:
https://github.com/mono/mono/blob/master/mono/mini/mini-runtime.c
It should be easy to add support for Erlang source file and
line mapping if we want to do that.
