In review of bbde6b, I had originally proposed that we support the legacy text format. As review evolved, it bacame clear this had been a bad idea (too much complexity), but in order to let that patch finally move forward, I approved the change with the variant. This change undoes the variant, and updates all the tests to just use the array form.

# This test checks to make sure that a DBG_VALUE that uses an immediate doesn't get zero-ed out by a DBG_VALUE that comes later in the basic block, and describes the same variable.
