Because IrPluginContextImpl constructor creates new instance of
BuiltinSymbolsBase (with symbols for stdlib declarations like `arrayOf` etc),
there should be at least one pass of `declareUnboundSymbolsAsDependencies`
between creation and usage in plugin. Such pass is located between psi2ir
and compiler plugins application. If plugin context is created inside lambda,
right before plugins are applied, the symbols will remain unbound.
