The testcase gives a good hint.

I'm about to send a set of patches that implement a simple memory model
for LLVM targets.  One of the things you would like to do with such a
model is specify sizes.  Since these sizes tend to be multiples of
powers of 2, it's more readable to talk about  12 * 1M, for example
rather than 12582912.
