Auto merge of #70163 - nikic:llvm-10-preparation, r=cuviper
Prepare for LLVM 10 upgrade
This is #67759 minus the submodule update.
* Fix two compatibility issues in the rustllvm wrapper.
* Update data layout strings in tests.
* Fix LLVM version comparison (this become a problem because the major version has two digits now).
