Stephane Eranian d892819faa perf/x86: Add support for PERF_SAMPLE_BRANCH_CALL 
This patch enables the suport for the PERF_SAMPLE_BRANCH_CALL
for Intel x86 processors. When the processor support LBR filtering
this the selection is done in hardware. Otherwise, the filter is
applied by software. Note that we chose to include zero length calls
because they also represent calls.
