rP505754: xen-{kernel/tools}: switch back to LLVM toolchain
Summary

Backport upstream fixes to correctly build Xen using LLVM 8 toolchain.

Note the fixes are not strictly needed for xen-tools since the Xen shim build is only ever supposed to be booted using the PVH entry point (and not the multiboot entry points). Yet given LLD8 erratic behaviour with orphan section placement I think it's best to ensure proper section placement for the shim also.
