fix #691.
in pervious modification, error.stack will be constructed in Error constructor, this will impact the performance of IE very badly, so in this PR, the auto-throw is removed.
fix #698.
when Error.stackTraceLimit is set to 0, the stack will be undefined, so we don't need to generate longstacktrace when stackTraceLimit = 0, it will improve performance in some test environment (such as some karma-test-shim for IE)
