Subject: dspspy: fix a bug with ConsoleHelper dspspy: remove some alignment
 for some vars. (should not have caused issues anyways) dspCodeUtil: pad
 ucodes converted to headers to 32byte multiples with nops (this is only
 mimicing what is seen in nintendo ucodes, probably because their's are
 originating on disc) Common.h: fix typo for gcc version of GC_ALIGNED32 (wtf?
 how did this work before?!) createtest.pl: add "jmp end_of_test" to the end
 of generated ucodes.
