When converting a block pointer to an Objective-C pointer type, extend
...
the lifetime of the block by copying it to the heap, or else we'll get
a dangling reference because the code working with the non-block-typed
object will not know it needs to copy.
There is some danger here, e.g. with assigning a block literal to an
unsafe variable, but, well, it's an unsafe variable.

Clean up the sentinel-attribute checking code a lot. Document

what 'nullPos' is supposed to mean, at least at this one site.
Use closed forms for the arithmetic. Rip out some clever but
ultimately pointless code that was trying to use 0 or 0L depending
the size of a pointer vs. the size of int; first, it didn't work
on LLP64 systems, and second, the sentinel checking code requires
a pointer-typed value anyway, so this fixit would not have actually
removed the warning.

Contextually converting to 'id' is not a useful operation. Contextually
...
converting to an arbitrary Objective-C pointer type is. Without
significantly re-implementing anything, change the API to reflect this,

potentially building it.
Mostly, this removes a really bizarre-looking bit of code from
BuildInstanceMessage.
