Separate patterns in asmcheck by spaces instead of commas. Many patterns end in comma (like "MOV [$]123,") so separating patterns by comma is not great; they're already quoted, so spaces are fine. Also replace all tabs in the assembly lines with spaces before matching. Finally, replace \$ or \\$ with [$] as the matching idiom. The effect of all these is to make the patterns look like: // amd64:"BSFQ" "ORQ [$]256" instead of the old: // amd64:"BSFQ","ORQ\t\\$256" Update all tests as well.
