Recommit "[CodeView] Emit static data members as S_CONSTANTs."
We used to only emit static const data members in CodeView as S_CONSTANTS when they were used; this patch makes it so they are always emitted. This changes CodeViewDebug.cpp to find the static const members from the class debug info instead of creating DIGlobalVariables in the IR whenever a static const data member is used. Bug: https://bugs.llvm.org/show_bug.cgi?id=47580 Differential Revision: https://reviews.llvm.org/D89072 This reverts commit 504615353f31136dd6bf7a971b6c236fd70582be.
