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".
