This significantly simplifies the implementation of editRequirements in preparation for making it lazy. It should have no effect on which version combinations are rejected by 'go get', nor on which solutions are found if downgrades are needed. This change results in a small but observable change in error logging. Before, we were reporting an error line for each argument that would have exceeded its specified version, attributing it to one arbitrary cause. Now, we are reporting an error line for each argument that would cause any other argument to exceed its specified version. As a result, if one argument would cause two others to exceed their versions, we will now report one line instead of two; if two arguments would independently cause one other to exceed its version, we will now report two lines instead of one. This change may result in a small performance improvement. Because we are now scanning and rejecting incompatible requirements earlier, we may waste less time computing upgrades and downgrades that ultimately won't matter due to conflicting constraints.
