Add some -X flags for compatibility to kotlin-reflect build

"-Xno-kotlin-nothing-value-exception" is needed to temporarily prevent
the problem happening in the composite build with Kotlin/Native
(ClassNotFoundException from KClassImpl.Data).
"-Xno-optimized-callable-references" is added just in case of any
similar problem.
