https://bugs.openjdk.java.net/browse/JDK-8057657

Add ability to annotate LambdaForm parameters with their types.
Type info could be useful during LambdaForm compilation to produce 
better bytecode.

Testing: jdk/java/lang/invoke, jdk/java/util/streams, nashorn, octane w/ 
"-ea -esa" and COMPILE_THRESHOLD={0,30}.
