Alex Richardson 7cab90a7b1 Fix __attribute__((annotate("")) with non-zero globals AS ...

The existing code attempting to bitcast from a value in the default globals AS
to i8 addrspace(0)* was triggering an assertion failure in our downstream fork.
I found this while compiling poppler for CHERI-RISC-V (we use AS200 for all
globals). The test case uses AMDGPU since that is one of the in-tree targets
with a non-zero default globals address space.
The new test previously triggered a "Invalid constantexpr bitcast!" assertion
and now correctly generates code with addrspace(1) pointers.
