profiler: add functions to plug linux Perf Event on JIT
Basically it creates a /tmp/perf-`pid`.map file which will contains a mapping of the x86 code with the EE/IOP/VU code * You need to enable the profiler with a define * You can split the profiling by block (inside a recomp buffer) v2: add new file to VS xml files v3: remove useless include
