Snapshot of this morning's returns
Fix two functions in which the result of realloc was not being captured correctly
Fix the additional string leaks detected with --baseline

Skipping dead code elimination leaves the array debugging calls to chpl__testPar
in the code (while the contents of this call would never be exercised because of
the appropriate boolean flag, the call is still made).  Since these calls send
in a message in the form of a string, additional memory leaks are generated.
To combat that, we now cast the message to our new string record - this seemed
fine because 1) only developers use chpl__testPar or baseline to our knowledge,
and 2) ChapelStandard already includes the NewString module so the cast was the
only thing that needed to be added.  When the string record is our default, this
cast will no longer be necessary and should be removed.

Address glibc memory error for some I/O routines

There were two points in the QIO library where the code is attempting to determine the
Current Working Directory using a posix routine that has an unfortunate buffer allocation
requirement.  The runtime code to manage this buffer allocation relied on realloc to grow
a buffer but then failed to assign the new memory to the buffer ptr.  However it did update
the buffer size.  This lead to a buffer overrun.

Compiled: Clang on darwin, GCC on linux
Tested: Verified the fix for types/file/freadComplex.chpl.  Temporarily reduced the initial buffer size of just 8 bytes and verified.  Ran the full regression suite.
