(11) RFR (S) JDK-8196884: VS2017 Multiple Type Cast Conversion Compilation Errors

[Lois Foltan]

Please review this fix for multiple type cast conversion compilation 
errors.  This fix includes a change to correctly type the symbolic 
constants badAddressVal and badOopVal in globalDefinitions.hpp and 
adjust numerous type cast conversions for the constant 0xdeadbeef.

Suggestions in the bug to remove the questionable remaining use of 
badOopVal as well as introduce a BAD_PTR macro definition for 0xdeadbeef 
have been filed as RFEs:
- Removal of BadOopVal https://bugs.openjdk.java.net/browse/JDK-8198308
- Introduce BAD_PTR https://bugs.openjdk.java.net/browse/JDK-8198309

Testing in progress (hs-tier1-3, jdk-tier1-3)

Thanks,
