Details: - Removed the line in each operation entry in input.operations titled "test sequential front-end" and the corresponding support for the lines in the testsuite input parsing code. This line was included in the some of the earliest versions of the testsuite, back when I intended to eventually have separate multithreaded APIs. Specifically, I envisioned that multithreaded and sequential testing could be enabled or disabled on an operation level. However, BLIS evolved in a different direction and still does not have multithreaded-specific APIs (even if it will eventually someday). But even if it did have such APIs, I doubt I would allow the user to enable/disable them on an operation level. Thus, this was a zombie future parameter that was never used and never made sense to begin with. The one instance of the front_seq variable, used in the various libblis_test_<operation>() functions to guard the call to the operation test driver, that remains was commented out instead of deleted so that someday it could be easily changed via sed, if desired. - Various minor cleanups to the testsuite code, including consolidating use of DISABLE and DISABLE_ALL and reexpressing certain conditional expressions in the libblis_test_<operation>() functions in terms of boolean functions.
