If a boolean type is compared to a string literal with
the value "true", it should just output that boolean
type unchanged (or prefixed with "not" if ifneq).

Instead of inserting a comment with error description into the generated code,
generate a call to a function that will print out a conversion error when executed.
Do not print generic "partially converted" message anymore.
Remove --verbose and --no_warnings options.

Previously, only comparisons between strings/variable references
and other strings/variable references or certain function calls
were allowed. After this cl, any two starlark expressions can
be compared. If they have different types, they will be converted
to strings first.
