Summary: This patch implements support for Intel(R) Processor Trace in lldb server. The changes have support for starting/stopping and reading the trace data. The code is only available on Linux versions where the perf attributes for aux buffers are available. The patch also consists of Unit tests for testing the core buffer reading function.
