  AMDGPU: Avoid crashing on statepoint-like pseudoinstructions

At the moment the MIR tests are somewhat redundant. The waitcnt
one is needed to ensure we actually have a load, given we are
currently just emitting an error on ExternalSymbol. The asm printer
one is more redundant for the moment, since it's stressed by the IR
test. However I am planning to change the error path for the IR test,
so it will soon not be redundant.
