Gang Li 448ce0e6ea perf stat: Enable ignore_missing_thread 
perf already support ignore_missing_thread for -p, but not yet
applied to `perf stat -p <pid>`. This patch enables ignore_missing_thread
for `perf stat -p <pid>`.

Committer notes:

And here is a refresher about the 'ignore_missing_thread' knob, from a
previous patch using it:

  ca8000684e ("perf evsel: Enable ignore_missing_thread for pid option")

  ---
    While monitoring a multithread process with pid option, perf sometimes
    may return sys_perf_event_open failure with 3(No such process) if any of
    the process's threads die before we open the event. However, we want
    perf continue monitoring the remaining threads and do not exit with
    error.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
