Summary: An llvm.dbg.declare of a static alloca is always added to the MachineFunction dbg variable map, so these values are entirely redundant. They survive all the way through codegen to be ignored by DWARF emission. Effectively revert r113967 Two bugpoint-reduced test cases from 2012 broke as a result of this change. Despite my best efforts, I haven't been able to rewrite the test case using dbg.value. I'm not too concerned about the lost coverage because these were reduced from the test-suite, which we still run.
