Merge branch 'egil/eprof' into dev
* egil/eprof: Fix eprof to handle error cases Dialyzer cleanup for eprof Fix fprof_SUITE to use new eprof API Switch pattern API for eprof profile with mfa Update eprof documentation Update eprof_SUITE with more basic tests Rename sorting choices for eprof Teach eprof to align text output Add dump functionality to eprof Add log functionality to eprof Update eprof tests to reflect new eprof Add start timestamp to eprof profiling Teach eprof to use the new breakpoints OTP-8706 egil/eprof eprof has been reimplemented with support in the Erlang virtual machine and is now both faster (i.e. slows down the code being measured less) and scales much better. In measurements we saw speed-ups compared to the old eprof ranging from 6 times (for sequential code that only uses one scheduler/core) up to 84 times (for parallel code that uses 8 cores).
