Add a linker script to version LLVM symbols Summary: This patch adds a very simple linker script to version the lib's symbols and thus trying to avoid crashes if an application loads two different LLVM versions (as long as they do not share data between them). Note that we deliberately *don't* make LLVM_5.0 depend on LLVM_4.0: they're incompatible and the whole point of this patch is to tell the linker that. Avoid unexpected crashes when two LLVM versions are used in the same process. Author: Rebecca N.
