Squash line numbers when comparing .bad and .comp.out.tmp files.

This patch is intended to cut down on some testing noise.

If tests report errors relative to module code and the module code has changed for other
reasons, line numbers in the .bad file will get out of sync.  This modification of
sub_test normalizes line numbers out of the comparison, under the assumption that
the exact line numbers in module code are not of particular interest.

This normalization affects only comparison with the .bad file (not the .good file).

Line numbers for errors arising in user (non-module) code are still matched verbatim.

To identify error messages, the sed script matches only lines containing
"CHPL_HOME/modules".  It then replaces the first string of digits between two colons with
"nnnn".
Add missing <eol> in diff-ignoring-module-line-numbers script.
Add .compopts file to genericArrayInClass-otharrs-inline-iterators test.

Put "--savec obj" in a .compopts file to make paths C compilation error messages more
stable, to support comparison against the .bad file.
Add genericArrayInClass-otharrs-inline-iterators.cleanfiles to clean up obj/

Add some new error messages for ref vars

Fatal error when using ref vars as members of classes/records.
Fatal error when ref vars are declared, but not initalized.
Fatal error when assigning a non-const ref to a const ref formal.
runtime/qio: use getcwd instead of getwd

Included code for handling errors.

Related to #325.
Update bug summary
Update ref var tests

Add two new futures:
test/variables/kbrady/ref-in-tuple.future
test/variables/kbrady/ref-member.future

Retire three old futures:
test/variables/sungeun/refvar-compare-nil.future
test/variables/sungeun/refvar-no-init-with-def.future
test/variables/sungeun/refvar-no-init-with-use.future

Suppress notifications from modern mac testing.

This will avoid lots of notifications to regressions list. This should be
reverted once the nondeterministic failures are fixed.
