Fix list_view() and aid() debugging tools.
Merge branch 'master' of https://github.com/chapel-lang/chapel
Added parSafe=false to a test
Fixed a minor glitch in each of sub_test and paratest.server
Save progress on exists functions.

Added a test and the basic set up for the exists function.  Have not implemented
it fully, so it will not compile correctly.  Saving progress so I can work on
bug fix week.
An initial version of jacobi-unroll.  Need to ask Ian and Cathie
about the fact that it still doesn't pass the correctness test.
Progress as of yesterday.
Followed up on David's feedback regarding aid(1).
Merge branch 'master' into exists

Make sure it is up to date with trunk.
Finish backend support of exists.  Also minor bug in the module code where
I had forgotten to pass along the filename from the error-throwing function to
the error-returning function.
strip newline for new comp perf .dat files

New comp perf .dat files were creaeted like:
#Date	perfKey

00/00/00	perfVal

this just removes the newline so there is no newline in a new .dat file
Forgot a new line, again.
Merge branch 'master' into exists
Adding a case to the test: the link exists, but is broken.
Add node ids to a few spots in the Node formatted output
Be more selective when handling blockStmt and then treat the WhileStmt condition expression in the same manner as C-For loop test
(a) handle a WhileStmt condition expression in the same manner as a C-For loop (b) WhileStmt needs some special cleanup comparable to C-For loop
Merge pull request #653 from ronawho/fix-comp-perf-dat-files

strip newline for new compiler perf .dat files

[trivial, not reviewed]

New comp perf .dat files were created like:

#Date perfKey

00/00/00 perfVal

this just strips a newline so there is no newline after the header in a new .dat file:

#Date perfKey
00/00/00 perfVal
Fix the directory calculation for when using paratesting.

With #647 I moved this block out of the if ($examples == 1) { block, but the
parnodefile piece should only be run inside the the block.

The concatenation of testdirs to testflags needs to happen outside, in case
CHPL_NIGHTLY_TEST_DIRS is set (and no flags are given).
Fix not equal string operator.
