deleting dead code, making other code more obvious, and fixing a

SemaExprObjC.cpp:383: warning: 'RHSProtoE' may be used uninitialized in this function
SemaExprObjC.cpp:383: warning: 'RHSProtoI' may be used uninitialized in this function

Use Digest::MD5 (a Perl module that should come bundled standard with Perl) to compute file digests instead of using the external program "sha1sum" (which may not be present).
