Cache text.size to improve performance for large strings

Change for_exprs_postorder so it stops when it reaches the passed-in expression.

The initial implementation of for_exprs_postorder did not contain a check to stop
iteration when the passed-in expression was reached, so iteration would continue up to the
root of the expression tree.  A check was added at the only place where for_exps_postorder
was used, to stop the iteration.  I moved the check inside the definition of
for_exprs_postorder, so it performs the iteration implied by its name.  This change should
not have any performance impact.

I also changed the signature of resolve_type_expression to return the resolved expression,
moving the error check from the end of that routine to its sole caller.  This positions
resolve_type_expression for use in other places in functionResolution, anticipating
changes introduced by user default constructor calls.
Revert "Add dirfiles/parallel."

Fix a bug in replicateGlobalRecordWrappedVars().

The existing implementation of replicateGlobalRecordWrappedVars() was written so that it
would skip the first block of the module initialization function when looking for the
definition of a global record-wrapped variable.  I modified the function to also look in
the first block.

The old version worked because by accident all the definitions of interest lay in blocks
following the first.  However, as part of the implementation of calling user default
constructors, I moved the initialization code for variables closer to where the variables
are declared.  In some cases, this resulted in interesting initialization code ending up
in the first block.

The change also made the total allocated memory in shannon/printFinalMemStat.chpl go down
by 64 bytes in the no-local case.  So I updated the .good file for that test.

Regex: Cache string size to improve performance for large strings in matches iterator

In the regex-dna shootout, we need to count the number of matches in a very large string. With the current state of strings, calling text.size invokes strlen. Calling strlen on this very large string every time we look for a match is very slow. By caching the string's length, the performance of this iterator improves immensely.

Small clean-ups to Regexp module.

- use .length instead of .size on string to be consistent and simplify
  logic surrounding some of those calls

- fix regexp:error() to return a string (was returning a c_string)

- fix _cast() -- did not work in the non-local case (I suspect there
  is no test case for this)

- added note on stringPart regarding possible use of c_string

Both changes here will bring chapel-lang/master into closer alignment with my callDefaultConstructors branch, simplifying the merge.

Mike noted that there using macros for procedural abstraction is somewhat undesirable, and I agree.  This is being committed as an intermediate solution: It should not be treated as definitive.

Small cleanups to Regexp module

[reviewed by Ben]

- Use string/c_string.length to be consistent throughout the file (it also reduces the work of function resolution and inlining slightly since .size calls .length and both are inlined)
- Simplify the stringPart specific logic surrounding the .length calls since now we use the same field name
- Comment a couple of places that seem like they needed stringPart logic but
- Add a comment for stringPart regarding the possible use of c_string rather than string
- Fix regexp:error() to return a string as the return type is specified (previously was returning c_string)
- Fix _cast() for multi-locale case (I suspect there is no test case for this)
