Chandler Carruth 63276ccdbd Do a better and more complete job of preserving metadata when combining ... loads. This handles many more cases than just the AA metadata, some of them suggested by Hal in his review of the AA metadata handling patch. I've tried to test this behavior where tractable to do so. I'll point out that I have specifically *not* included a test for debuginfo because it was going to require 2 or 3 times as much work to craft some input which would survive the "helpful" stripping of debug info metadata that doesn't match the desired schema. This is another good example of why the current state of write-ability for our debug info metadata is unacceptable. I spent over 30 minutes trying to conjure some test case that would survive, even copying from other debug info tests, but it always failed to survive with no explanation of why or how I might fix it. =[ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220165 91177308-0d34-0410-b5e6-96231b3b80d8		2014-10-19 10:46:46 +00:00
