New Revision: 155386

URL: http://llvm.org/viewvc/llvm-project?rev=155386&view=rev
Log:
Beginning of fix for PR#12639: Add support for the blockaddress constant.
This code simply adds a DSNode with the Unknown flag for the blockaddress
constant.  In the future, we should probably add a Blockaddress flag to the
set of DSFlags.
