Fix for fuzzer-discovered error with invalid var-initializers. If a VarDeclaration line contained multiple variables, and the first variable had an illegal initializer-expression, the Declare() would return a Nop. AddVarDeclaration did not expect to see a Nop and would assert once we tried to process the second var-declaration. Now, we allow adding var declarations to a Nop. Bulked up some tests to cover local and global variables (since those are parsed in separate functions) and to check both the first initializer as well as follow-on initializers (since those are parsed in separate parts of the var-decl handler).
