Bob Haarman 54290459aa Reland r311957 [codeview] support more DW_OPs for more complete debug info ... Summary: Some variables show up in Visual Studio as "optimized out" even in -O0 -Od builds. This change fixes two issues that would cause this to happen. The first issue is that not all DIExpressions we generate were recognized by the CodeView writer. This has been addressed by adding support for DW_OP_constu, DW_OP_minus, and DW_OP_plus. The second issue is that we had no way to encode DW_OP_deref in CodeView. We get around that by changinge the type we encode in the debug info to be a reference to the type in the source code. This fixes PR34261. The reland adds two extra checks to the original: It checks if the DbgVariableLocation is valid before checking any of its fields, and it only emits ranges with nonzero registers.
