[LLVMdev] perf tool support in MCJIT

[Jose Fonseca]

FWIW, Mesa3D has some LLVM <-> linux perf integration (and disassembly output too).  This responsibility can and probably should be moved upstream to LLVM though.

For more information see:
  http://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/auxiliary/gallivm/lp_bld_debug.cpp#n411
  http://cgit.freedesktop.org/mesa/mesa/tree/bin/perf-annotate-jit
