Do not use PropagateLineInfoPass and RedundantLineInfoElimPass (#2440)

Browse source 
* Do not use PropagateLineInfoPass and RedundantLineInfoElimPass

Since spirv-opt will remove PropagateLineInfoPass and
RedundantLineInfoElimPass, glslang should not use it. spirv-opt will
propagate the line instructions and eliminate the redundant lines by
default in IR loading/emission.

* Update known_good.json for spirv-tool
