Create polymorph_with_Softbound.c

This source code file should be used instead of polymorph.c  to compile with clang compiler with Softbound support. Rename source file polymorph_with_Softbound.c to polymorph.c and then use the following command: 

<your_dir>$ clang -fsoftboundcets polymorph.c -o polymorph -L /home/softbound64bit/Desktop/Softbound/softboundcets-34/softboundcets-lib -lm -lrt

Warning: Rename path to library /home/softbound64bit/Desktop/Softbound/softboundcets-34/softboundcets-lib  to your own path on your machine. Malicious input for polymorph is detected by Softbound at runtime and polymorph was aborted.
