Adjust DatumGetBool macro, this time for sure. Commit 23a41573c attempted to fix the DatumGetBool macro to ignore bits in a Datum that are to the left of the actual bool value. But it did that by casting the Datum to bool; and on compilers that use C99 semantics for bool, that ends up being a whole-word test, not a 1-byte test. This seems to be the true explanation for contrib/seg failing in VS2015. To fix, use GET_1_BYTE() explicitly. I think in the previous patch, I'd had some idea of not having to commit to bool being exactly 1 byte wide, but regardless of what the compiler's bool is, boolean columns and Datums are certainly 1 byte wide.
The previous fix was (eventually) back-patched into all active versions, so do likewise with this one.
