Convert BlockStmt::blockInfo to a private member variable.  As first pass replace read/writes with calls to a generic virtual getter/setter.
When building basic blocks for loop, only put the test expression at the top of the loop body; not the entire blockInfo callExpr for C-For loops
Iterators with C-For loops need to capture the loop init variables as Iterator fields.  This was being done implicitly in BB.cpp.  Now it's explicit here
DCE can create degenerate nodes.  Add a post-pass to clean these up so that they don't propagate
Add a future related to using a type alias for construction of a type instance.

Though basic type aliases can be used, if the alias assigned is a result of a
function, the Chapel compiler will crash.
Whoops, need trailing line.
Delete the current test config naming code in nightly, and support CHPL_NIGHTLY_TEST_CONFIG_NAME env var.
oc email formatting...
Make it clear not setting test config name is an error.

Add "Tests run:" section to nightly cron emails.
Add CHPL_NIGHTLY_TEST_CONFIG_NAME to all util/cron/test*.bash scripts.
Perform C-For loop cleanup after every Function
Fix execopts and compopts processing for paratest.server

Mike noticed that if you have something like paratest.server -compopts --llvm
-compopts --verify, that only --verify was picked up. The reason is pretty
simple and was that every time a compopts/execopts was found, it overrode the
previous value instead of concatenating. This just updates execopts and
compopts processing to concatenate instead of overriding. For all the other
arguments, overriding makes sense.
Make compopts/execopts have leading instead of trailing space for paratest

Makes it easier to read the code, and matches what we do in start_test, has no
affect on functionality
whoops, committed .swp files
Correctly handle CHPL_NIGHTLY_TEST_DIRS.
Include printchplenv output at end of cron emails.
Rename whitebox testing scripts.
Add new test config names for whitebox testing.
