This is V3 of: https://sourceware.org/ml/gdb-patches/2018-08/msg00243.html

There are some minor changes compared to V2, following the suggestions there:

* Added a comment to "Zero-initialize linux note sections"

* De-duplicated testcase names.  Changed a few of the test names so
  that they are environment-independent.  Fixed a few other minor
  issues with the testcases.

* Fixed some of the formatting and const-correctness in "[PowerPC] Add
  support for HTM registers", in gdbserver/linux-ppc-low.c.

* Added an item in the NEWS file on the last commit, indicating all
  the newly supported registers from this series.

One missing change above:

* Changed one of the testcases for the HTM registers so that it XFAILs.
  This testcase occasionally failed, possibly due to a kernel bug.
