Add an example of using the targetLocales method on arrays
Fix passing sync/single variables by ref/blank intent.
Merge branch 'master' of github.com:chapel-lang/chapel into dist-primer-lsq
Adding exampels for the 'localSubdomain(s)' functions
Followed up on reviewers' comments.
Added tests. Retired a future.
Added another isX test; strengthened type-tests.chpl.
type-tests.todo.chpl is now covered by type-tests.chpl,
so I removed it.
More test adjustments.
Also allowed sync/singles in tuple *types*
- see parallel/sync/diten/tupleOfSync.chpl
Fix for io_test C compilation error.

The error message being displayed by the C compiler (GCC version 4.4.1 or newer) is
meaningful.  It warns that the program is attempting to free something that is not
heap-allocated -- in this case "\n" and the definitions of other ioLiterals.

The reason why the error only appears when --fast is supplied is that aggressive inlining
brings the call to free() into the function where an ioLiteral is passed to it, so under
those circumstances the C compiler can see that something stupid is being attempted.

In the original code, the author thought is was safe to free by explicitly avoiding known
cases where the contents of a c_string was owned by another program entity.  However,
since the IO module also supplies unowned c_strings it is unsafe in general to delete
them.  I added comments liberally to the module code where c_strings are accessed, so
future programmers are warned away from this practice.

Looking forward, except where performance is a concern, strings should be used in
preference to c_strings.  The new implementation of strings will manage memory correctly,
so the programmer who uses such objects need not concern himself with ownership details.
Followed up on the second round of Brad's comments.

Two TODOs:
* [ ] David's review of test/modules/diten/moduleNotInitialized.chpl
* [ ] why passing sync/single by reference is specific to ref/blank intents?
Merge branch 'master' into fixCStrings
Example for Cyclic; Example for 'localSubdomains' on Block
Followed up on Brad's latest comments and group discussion.
* writeThis() is a compile-time error on sync/single
* corresponding test changes - added readFE/readFF when writing
* moved max() error testing from error-min-on-syncs.chpl into separate file
* adjusted an error message to say 'currently'
Add a primer for array vector operations

This primer walks through the new vector-like capabilities on 1D arrays.

Work around lack of kernel scheduling affinity on KNC compute nodes.

The KNC compute nodes we have access to seem not to have kernel affinity
scheduling present.  Either that, or perhaps it's confused: we get masks
with no bits set returned from sched_getaffinity().  To work around this
for now, just don't apply the scheduling affinity limiting in the two
functions that return the number of physical and logical CPUs, even if
the caller passes the flag saying to pay attention to that.  (Note that
we also ignore this flag for all the non-Linux targets at present, so
there is precedent here.)
Updating re2 build to use -mmic for intel+knc builds

Following the lead of other third-party Makefiles, if we're building for
KNC using the intel compiler, throw the -mmic flag when building re2.
While here, I did some other cleanup:

* broke a long line of commands across several lines
* passed CXX into both recursive make steps just for symmetry (I don't
  believe it's used for the install step)
* removed the set of CC as it doesn't seem to be used by re2's Makefile

More test updates - add readFE/readFF when writing sync/single.

I used readFF() on a sync, instead of readFE, in a few cases
where the computation is over, to say ''read the value and
keep it there just in case''.

I also slightly updated the sync/single primer with sync/single
generic formals, mention we can't just write them, added
some clearly missing newlines.
