[DebugInfo] getMergedLocation: Maintain the line number if they match

getMergedLocation returns a 'line 0' DILocaiton if the two locations
being merged don't perfecly match, even if they are in the same line but
a different column.

This commit adds support to keep the line number if it matches (but only
the column differs). The merged column number is the leftmost between the
two.
