Pekka Enberg 80d496be89 perf report: Add support for profiling JIT generated code 
This patch adds support for profiling JIT generated code to 'perf
report'. A JIT compiler is required to generate a "/tmp/perf-$PID.map"
symbols map that is parsed when looking and displaying symbols.

Thanks to Peter Zijlstra for his help with this patch!

Example "perf report" output with the Jato JIT:

 #

 # Overhead           Command  Shared Object              Symbol
 # ........  ................  .........................  ......
