  -----------
  [AMDGPU] Pre-commit test for constant-offset named barrier signal_var

A GEP into a named-barrier array (&bars[1]) lowers s_barrier_signal_var to
the dynamic m0 form on SelectionDAG, unlike the bare global and GlobalISel.
With object linking it emits a runtime add of the offset instead of folding
it into the relocation addend.

Also add a misaligned-offset test: a byte GEP that does not land on a
barrier boundary is valid IR and must not crash the compiler.
