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.

# The purpose of this test is to check that long branches are selected correctly
|
|
# when we have prefixed instructions that may require alignment. Prefixed
|
|
# instructions may require alignment and so an additional 4 bytes may be added.
|
|
# If those 4 bytes put the target of the branch past the range of a short branch
|
|
# then we should use a long branch like in this test.
