Improve the version/flags extract from interface file by moving away from using Regex and limiting the search to the beginning of the file. Switch away from Regex will give 5-10% improvement in time and instruction counts, and limiting the search lines can save a lot of time if the swiftinterface is large. For example, the extract time for Swift stdlib is 10x faster after the patch. Current strategey for limiting the line to search is by only parsing the first comment block.
