Lagom: Add clang address/memory/undefined-behavior analyzer support

Browse source 
Adding the ability to turn on Clang analyzer support in the Lagom build.
Right now the following are working warning free on the LibJS test suite:

 -DENABLE_MEMORY_SANITIZER:BOOL=ON

 -DENABLE_ADDRESS_SANITIZER:BOOL=ON

The following analyzer produces errors when running the LibJS test suite:

 -DENABLE_UNDEFINED_SANITIZER:BOOL=ON
