Reviewed by Keith Miller and Mark Lam.
This patch extends sampling profiler output as followings.
1. We add `sources` section. It is array of source, and each one may have url,
sourceURL, and sourceMappingURL.
{
sourceID: <integer source id>,
url: <url string from WebKit / JavaScriptCore. optional>,
sourceURL: <sourceURL string specified via comment directive. optional>,
sourceMappingURL: <sourceMappingURL string specified via comment
directive. optional>
}
2. Add line and column information. If they are not found, it is UINT32_MAX
(0xffffffff).
