[MERGE #2644 @jianchun] perf test script fixes

Merge pull request #2644 from jianchun:perfscript

Add "WScript.Echo" definitions to all SunSpider js files to support
non-Chakra hosts.

`perftest.pl`:
- Fix dir name cases.
- Change to "-?" in test_switch ("/?" not supported on xplat).
- Add "-testfile:<file>" switch to save perf test result to a file as well,
  by default to "perftest???.txt". This is useful if we want to use the
  test numbers as baseline for subsequent perf runs.
- Add "-skipCheckSwitch" to support non-Chakra hosts. It is not meaningful
  to test for Chakra switches, and in addition may run into trouble (host
  may start command loop instead of exit).
