Summary: llc -O0 generates incorrect debug information when
compiling IR containing llvm.dbg.value

minimized llvm IR
If you take the attached LLVM IR containing debug information and try to
compile it into an executable using `llc -O0`, GDB (tested using version 9.2)
will not be able to report the value of `x` if you are stopped at a breakpoint
on the `foo` function. This seems to have worked as recently as llvm 11. This
is on an AMD64 machine. I can reproduce this on the main branch of llvm.
