Add test cases for the z13 vector FP support. Bring s390-opcodes.csv
up-to-date, reflecting that the z13 vector instructions are now supported.
Also remove the non-support disclaimer for the vector facility from
README.s390.
The patch was contributed by Vadim Barkov, with some clean-up and minor
adjustments by Andreas Arnez.

Use inlined frames in Massif XTree output.
This makes Massif's output much easier to follow.
The commit also removes a -1 used on all Massif stack frame addresses.
There was a big comment questioning the presence of that -1, and with it
gone the addresses now match those produced by DHAT.
* Create the 3.15 section in the NEWS file
(the idea is that this section is maintained during the development,
i.e. document user visible changes and/or the fixed bugs, as part of
the commit).
* start the fixed bug list with 399322 Improve callgrind_annotate output
* update vg-entities.xml for 3.15 next release.
This adds test cases and some internal stuff to the z/Architecture vector
integer and string instruction support.

This adds z/Architecture vector integer and string instruction support.
The main author of this patch is Vadim Barkov <vbrkov@gmail.com>. Some
fixes were provided by Andreas Arnez <arnez@linux.ibm.com>.
This implements various z/Architecture instructions that conditionally
yield a data exception ("trap"). The condition is either based on a
comparison being true ("compare and trap") or on a loaded value being
zero ("load and trap"). These instructions haven't been widely used in
the past, but may now be emitted by newer compilers. Note that the
resulting signal for a data exception is SIGFPE, not SIGTRAP. Thus this
patch also adds a new jump kind Ijk_SigFPE.
(from bug 385408 comment 0):
Valgrind currently lacks support for the z/Architecture vector "support"
instructions introduced with z13. These are documented in the
z/Architecture Principles of Operation, Eleventh Edition (March, 2015),
chapter 21: "Vector Overview and Support Instructions".
Fixes BZ#374963.
Previously Valgrind failed to start when the executable contained
large text, data or bss segments. The load address was increased
for almost all platforms to 0x58000000 (from 0x38000000),
giving another 512 MB for the executable.
