Start doing more validation of intrinsics: assert, new, delete, rand (#2766)

Browse Source 
This is adding more validation of intrinsics. It addresses a bug in rand where CHECK-fails would occur for bad range inputs, instead of a runtime error. I'm also addressing what I think was an int32 range issue in the handling by running the generator with int64.
