Sanjoy Das b9faf7c64f [StackMaps] Increase the size of the "location size" field 
Summary:
In some cases LLVM (especially the SLP vectorizer) will create vectors
that are 256 bytes (or larger).  Given that this is intentional[0] is
likely to get more common, this patch updates the StackMap binary
format to deal with the spill locations for said vectors.

This change also bumps the stack map version from 2 to 3.
