[opaque pointer type] Add textual IR support for explicit type parameter to gep operator

Similar to gep (r230786) and load (r230794) changes.

Similar migration script can be used to update test cases, which
successfully migrated all of LLVM and Polly, but about 4 test cases
needed manually changes in Clang.

(this script will read the contents of stdin and massage it into stdout
- wrap it in the 'apply.sh' script shown in previous commits + xargs to
apply it over a large set of test cases)

  return line

line = sys.stdin.read()

for match in re.finditer(rep, line):
