Alex Richardson 9114ac67a9 Overload all llvm.annotation intrinsics for globals argument
The global constant arguments could be in a different address space
than the first argument, so we have to add another overloaded argument.
This patch was originally made for CHERI LLVM (where globals can be in
address space 200), but it also appears to be useful for in-tree targets
as can be seen from the test diffs.
