Adrian Hunter 116f349c5b perf intel-pt: Make logging slightly more efficient
Logging is only used for debugging. Use macros to save calling into the
functions only to return immediately when logging is not enabled.

Adrian Hunter 53af92849d perf tools: Add Intel PT log
Add a facility to log Intel Processor Trace decoding.  The log is
intended for debugging purposes only.

The log file name is "intel_pt.log" and is opened in the current
directory.  The log contains a record of all packets and instructions
decoded and can get very large (10 MB would be a small one).
