Setup for / analyze code analysis , which we currently only have on the 360 , but
we may get later for win32 if we buy the higher end vc + + licenses .
Even with VS2010 ultmate , / analyze only works for x86 , not x64
Also note the __analysis_assume macro in sys_assert . h relates to code analysis .
This header should be included even by job code that doesn ' t reference the
bulk of the codebase , so it is the best place for analyze pragmas .
