Author: Rob Latham <robl at mcs.anl.gov>

a "large contig" type
despite promoting types throughout the gather path, still had one case of
constructing structs with larger-than-int blocklens. solution: borrow BigMPI
strategy and construct types-of-chunks to get around limitations.

promote more types to larger versions
The ongoing march towards 64-bit clean continues. Address areas where large
product of two ints might have overflowed.

commit 5e67e4824d1d7f4c007f6860c6a628e6aac6ef63
Author: Rob Latham <robl at mcs.anl.gov>
Date: Fri Jun 12 10:28:57 2015 -0500
fixes for test case
- preprocessor constants need parens
- which showed the "always fail" case wasn't big enough
- compiler warned about variables possibly being used uninitialized
Ref: #1767
