In an effort to fix inlined debug info in situations where the out of line definition of a function preceeds any inlined usage, the order in which some attributes are added to subprogram DIEs may change. (in essence, definition-necessary attributes like DW_AT_low_pc/high_pc will be added immediately, but the names, types, and other features will be delayed to module end where they may either be added to the subprogram DIE or instead reference an abstract definition for those values) These tests can be generalized to be resilient to this change. 5 or so tests actually have to be incompatibly changed to cope with this reordering and will go along with the change that affects the order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209554 91177308-0d34-0410-b5e6-96231b3b80d8
