perf tools: Fix bug in isupper() and islower() One of the reasons 'perf test' is failing on Power appears to be due to a bug in isupper(). isupper(c) and islower(c) should be checking 'c' against the mask 0x20. Instead they are checking sane_ctype[c] which causes isupper() to be true for lower case letters.
