Summary: Ensure dynamic properties are created in instances

Bugs Fixed: LPP-8088  DHTML: many warnings from  
applyConstraintMethod() (partial)

Technical Reviewer: max (pending)
QA Reviewer: hminsky (pending)

Details:
     Clean up the code in LzNode that makes sure dynamic properties
     exist by using a cross-platform test:  if accessing the dynamic
     property returns undefined, make sure it exists in the instance by
     setting it to undefined.

     This does not fix the warning part of the bug, but it does make
     swf9 work again.

Tests:
     http://localhost:8080/4.2/test/extensions/html.lzx?lzr=swf9 No
     longer gets a runtime error.

Files:
M      WEB-INF/lps/lfc/core/LzNode.lzs
