Forall intents - the initial implementation.
Add parallel execution of make to lots of testing scripts.
Do not use parallel execution when calling `make check`.

start_test breaks because the backend C build (inside chpl compiler) calls
make. However, when that make starts up, it assumes it is a submake and
attempts to communicate with a job server that does not exist. There is
probably some way to fix that (one thought is to set .NOTPARALLEL in the
Makefile.exe), but it is simple enough to call regular make with parallel
execution and then make a second call to make check.

Improve error handling in nightly when CHPL_NIGHTLY_LOGDIR is not set.

* Report error and exit with non-zero code if CHPL_NIGHTLY_LOGDIR is not set
  (or empty) in -cron mode.
* Try to create the logdir, if it does not exist already (for both -cron and
  -debug modes).
* Check that directory is accessible in both -cron and -debug modes.

Some of these things were already done in -debug mode.

Last week I had started reworking my noinit tests now that _defaultOf is in the
repository.  This is just storing all those changes until I can get back to it
Number of edits:
1) re-renamed the 1D/2D situation.
   Names reflect the data dimensionality, and not the dimensionality of the tile.
2) Unified graphs by dimension. There is now only a Jacobi-1D and Jacobi-2D graphs.

Reverted an inintended change in 82bda416.
Let a script override testEnv in sub_test &c.
Merge branch 'skipifAsScript' of github.com:hildeth/chapel into skipifAsScript
Several things:
1) re-renamed files, from plain "Diamond-Tiling" to "Sliced-Diamond-Tiling"
   I figured that this will ease some headaches when we get regular, unsliced Diamond Tiling
2) Added the OpenMP C versions for 1- & 2-D, of Naive-Parallel and Sliced-Diamond-Tiling
Add tests for result == "True" per Thomas' request.
