This patch changes some of the dejagnu options to better restrict
where the test cases run so that they will no longer cause failures on
power7 machines.
Based on a subsequent patch I also updated the code formatting (indentation,
etc.) for the code from the original patch (r235577) in both the test cases
and in rs6000-c.c.

X86 Linux kernel is compiled only with integer instructions. Currently,
-mno-sse -mno-mmx -mno-sse2 -mno-3dnow -mno-avx -mno-80387
-mno-fp-ret-in-387 -mskip-rax-setup
is used to compile kernel. If we add another non-integer feature, it
has to be turned off. We can add a -mgeneral-regs-only option, similar
to AArch64, to disable all non-integer features so that kernel doesn't
need a long list and the same option will work for future compilers.
It can also be used to compile interrupt handler.

This patch adds support for the signed and unsigned int versions of the
vec_addec altivec builtins from the Power Architecture 64-Bit ELF V2 ABI
OpenPOWER ABI for Linux Supplement (16 July 2015 Version 1.1). There are
many of the builtins that are missing and this is part of a series
of patches to add them.
There aren't instructions for the int versions of vec_addec so the
output code is built from other built-ins that do have instructions
which in this case is the following.
vec_addec (va, vb, carryv) == vec_or (vec_addc (va, vb),
vec_addc(vec_add(va, vb),
vec_and (carryv, 0x1)))
The new test cases are executable tests which verify that the generated
code produces expected values. C macros were used so that the same
test case could be used for both the signed and unsigned versions. An
extra executable test case is also included to ensure that the modified
support for the __int128 versions of vec_addec is not broken. The same
test case could not be used for both int and __int128 because of some
differences in loading and storing the vectors.
Bootstrapped and tested on powerpc64le-unknown-linux-gnu and
powerpc64-unknown-linux-gnu with no regressions. Is this ok for trunk?

This patch implements support for marking CALL_EXPRs
as being mandatory for tail-call-optimization. expand_call
tries harder to perform the optimization on such CALL_EXPRs,
and issues an error if it fails.

so the patch uses a plugin for testing the functionality.

A common way for a c_expr to have an uninitialized src_range is in
error-handling, where the "value" field is set to error_mark_node
without touching the src_range, leading to complaints from valgrind.
This patch introduces a new method c_expr::set_error which sets
the value to error_mark_node whilst initializing the src_range to
UNKNOWN_LOCATION.
This fixes the valgrind issue seen in PR c/71171, along with various
other related issues seen when running the testsuite using the
checker patch I posted here:
https://gcc.gnu.org/ml/gcc-patches/2015-12/msg00887.html
(this checker still doesn't fully work yet, but it seems to be good
for easily detecting these issues without needing Valgrind).
