klee/0003-test-add-versions-of-some-tests-for-LLVM-3.7.patch

From: =?UTF-8?q?Richard=20Trembeck=C3=BD?= <richardt@centrum.sk>
Date: Fri, 29 Apr 2016 22:33:41 +0200
Subject: test: add versions of some tests for LLVM 3.7
Patch-mainline: no

Clone some tests to have their 3.7 version. 'call's, 'load's and
'getelementptr's match the new specification in them.

@andreamattavelli: Fixed test cases: BitCastAlias test cases included
modification to alias specifications that require LLVM 3.8

[v2] added comments what was changed and why
