test: add versions of some tests for LLVM 3.7
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 [v3] the new tests are without suffix, the old ones have ".leq36".
