<pre>Environment: Windows 8 x64.
On some machines all goes well when using MCJIT but on others there is an
assertion failure on assert(isInt<32>(RealOffset)); in RuntimeDyidELF.cpp
However if we explicitly set code and relocation model when we create
ExecutionEngine - then assertion is not triggered and everything is fine:
.setCodeModel(llvm::CodeModel::Large)
.setRelocationModel(llvm::Reloc::Static)
Probably the following issues are related:
