; Test if internal global variable's debug info is merged appropriately or not.
DebugInfo: New metadata representation for global variables. This patch reverses the edge from DIGlobalVariable to GlobalVariable. This will allow us to more easily preserve debug info metadata when manipulating global variables. Fixes PR30362. A program for upgrading test cases is attached to that bug.

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144

; CHECK: [[DI1]] = !DIGlobalVariableExpression(var: [[V1:.*]], expr: !DIExpression())
[IR] Remove the DIExpression field from DIGlobalVariable. This patch implements PR31013 by introducing a DIGlobalVariableExpression that holds a pair of DIGlobalVariable and DIExpression. Currently, DIGlobalVariables holds a DIExpression. This is not the best way to model this: (1) The DIGlobalVariable should describe the source level variable, not how to get to its location. (2) It makes it unsafe/hard to update the expressions when we call replaceExpression on the DIGLobalVariable. (3) It makes it impossible to represent a global variable that is in more than one location (e.g., a variable with multiple DW_OP_LLVM_fragment-s). We also moved away from attaching the DIExpression to DILocalVariable for the same reasons. This reapplies r289902 with additional testcase upgrades and a change to the Bitcode record for DIGlobalVariable, that makes upgrading the old format unambiguous also for variables without DIExpressions. <rdar://problem/29250149> https://llvm.org/bugs/show_bug.cgi?id=31013 Differential Revision: https://reviews.llvm.org/D26769 llvm-svn: 290153

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.
