; PR6112 - When globalopt does RAUW(@G, %G), the metadata reference should drop
Fix a variant of PR6112 found by thinking about it: when doing RAUW of a global variable with a local variable in function F, if function local metadata M in function G was using the global then M would become function-local to both F and G, which is not allowed. See the testcase for an example. Fixed by detecting this situation and zapping the metadata operand when it occurs. llvm-svn: 103007

; to null. Function local metadata that references @G from a different function
; to that containing %G should likewise drop to null.
