Dstress summary suggestion

[Don Clugston]

It would be nice if, in the summary page, the 'hotspots' listing 
indicated whether the failures are independent of the command-line 
options, or specific to some of them (ie, only show up in 'torture' 
test). In the boxes where it says "XPASS", "FAIL", etc, it could display 
"XPASS+", "FAIL+", "ERROR+" instead, if there were some command-line 
options where it passed.

Most cases with a + are likely to be Linux-specific, so this would make 
dstress more indicative for Windows DMD.

You could even split the them up that way in the summary, this would 
show that the big change between dmd 0.144 and 0.145 was that most of 
ERROR+ became PASS, whereas ERROR probably didn't change much. This 
would make comparisons between gdc and dmd more precise.
