Jeremy Morse b2c5377fb4 [DebugInfo] Use zero linenos for debug intrinsics when promoting dbg.declare ... In certain circumstances, optimizations pick line numbers from debug intrinsic instructions as the new location for altered instructions. This is problematic because the line number of a debugging intrinsic is meaningless (it doesn't produce any machine instruction), only the scope information is valid. The result can be the line number of a variable declaration "leaking" into real code from debugging intrinsics, making the line table un-necessarily jumpy, and potentially different with / without variable locations. Fix this by using zero line numbers when promoting dbg.declare intrinsics into dbg.values: this is safe for debug intrinsics as their line numbers are meaningless, and reduces the scope for damage / misleading stepping when optimizations pick locations from the wrong place.
