Russ Cox 915c1839fe test/codegen: simplify asmcheck pattern matching
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.
