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.
