e1c53f29d3 Split DbgVariable. Eventually, variable info will be communicated through frame index, or DBG_VALUE instruction, or collection of DBG_VALUE instructions. Plus each DbgVariable may not need a label.

This means now 'llvm-ld a.bc b.bc' will preserve debug info appropriately.

7421ae48bf Disable the new unknown-location code for now. It causes a major
increase in the debug line info section, and it's causing
regressions in a gdb testsuite.

50849c63e4 Emit debug info for MachineInstrs with unknown debug locations, instead
of just letting them inherit the debug locations of adjacent instructions.

Debug info should aim to be either accurate or absent.
