This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
gdb.base/gnu_vector.c printf the vector and gdb.base/gnu_vector.exp
expects the output by gdb_test_multiple. Nowadays, the test doesn't
expect the output from inferior_spawn_id, which is wrong. Even we
change the test to expect from inferior_spawn_id for the inferior
output, it is still possible the inferior exit before tcl/expect gets
the inferior output. We see this fail on both s390x-linux and
ppc-linux on buildbot,
FAIL: gdb.base/gnu_vector.exp: verify vector return value (the program exited)

In order to address these two shortcomings above in gnu_vector.exp,
this patch rewrites the test a little bit. Get rid of checking the
inferior output, and instead checking them by printing them. In this
way, the test can also be run on the target without inferior io
(gdb,noinferiorio is set in the board file).
gdb/testsuite:

* gdb.base/gnu_vector.exp: Check the return value by "p res".
* gdb.base/gnu_vector.c: Don't include stdio.h.
(main): Don't print res and call add_some_intvecs.
So far the gnu_vector test was limited to "static" aspects of GDB's
vector support, like evaluating vector-valued expressions. This patch
enriches the test and adds checks for GDB's vector ABI support as well.
The new checks particularly verify inferior function calls with vector
arguments and GDB's handling of vector return values.
The test now attempts to compile for the target's "native" architecture,
such that a hardware vector ABI is used if available.
Since GDB has no vector ABI support for x86 and x86_64 targets, most of
the new checks are KFAILed there.
gdb/testsuite/ChangeLog:
* gdb.base/gnu_vector.c: Include stdarg.h and stdio.h.
(VECTOR): New macro. Use it...
(int4, uint4, char4, float4, int2, longlong2, float2, double2):
...for these typedefs.
(int8, char1, int1, double1): New typedefs.
(struct just_int2, struct two_int2): New structures.
(add_some_intvecs, add_many_charvecs, add_various_floatvecs)
(add_structvecs, add_singlevecs): New functions.
(main): Call add_some_intvecs twice.
* gdb.base/gnu_vector.exp: Drop GCC version check; just attempt
the compile and exit upon failure. Try compiling for the "native"
architecture. Test inferior function calls with vector arguments
and vector return value handling with "finish" and "return".
gdb/ChangeLog
* valarith.c (value_vector_widen): New function for replicating a
scalar into a vector.
(value_binop): Use value_vector_widen to widen scalar to vector
rather than casting, this better matches gcc C behaviour.
* valops.c (value_casst): Update logic for casting between vector
types, and for casting from scalar to vector, try to match gcc C
behaviour.
* value.h (value_vector_widen): Declare.
* opencl-lang.c (opencl_value_cast): New opencl specific casting
function, handle special case for casting scalar to vector.
(opencl_relop): Use opencl_value_cast.
(evaluate_subexp_opencl): Use opencl_value_cast instead of
value_cast, and handle BINOP_ASSIGN, UNOP_CAST, and UNOP_CAST_TYPE
in order to use opencl_value_cast.
gdb/testsuite/ChangeLog
* gdb.base/gnu_vector.c: New variable for use in tests.
* gdb.base/gnu_vector.exp: Update and extend tests to reflect
changes in scalar to vector casting and widening.
* gdb.python/py-type.c: New variables for use in tests.
* gdb.python/py-type.exp: Update vector related tests to reflect
changes in scalar to vector casting and widening.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
