… LHS
IEEE 1800-2017 6.10 declares an undeclared identifier used on the LHS of a
continuous assignment as an implicit net of the default net type.
convert_continuous_assign already did this for a bare-identifier LHS but not
when the identifier appeared as a member of a concatenation, e.g.
assign {carry, sum} = a + b; // carry is undeclared
which was rejected with "unknown identifier". Declare each undeclared
bare-identifier member as a scalar net before converting the concatenation.
Fixes LogikBench arithmetic/sub.

Split out from #2052 (root cause 2 of the LogikBench type-checker triage).
