Currently, llvm-symbolizer doesn't like to parse .debug_info in order to show the line info for global variables. addr2line does this. In the future, I'm looking to migrate AddressSanitizer off of internal metadata over to using debuginfo, and this is predicated on being able to get the line info for global variables. This patch adds the requisite support for getting the line info from the .debug_info section for symbolizing global variables. This only happens when you ask for a global variable to be symbolized as data. Reviewed By: dblaikie Differential Revision: https://reviews.llvm.org/D123538
