Crash in verifier llvm-as

Version is 21.1.0-rc3 (but also on version 20)
Although some versions seemed to work, the most suspicious recent changes are:

• a [16 x i16] constant is linked as extern uint16_t[] in some C code (pre-compiled with Clang)
• a [16 x ptr] constant is linked as extern **uint64_t[], each element is a pointer to some constant (private) arrays
• llvm.experimental.gc.statepoint.p0 has a variety of ids ,but uses i64 0 most of the time, whereas before we only ever used 0

I believe these work without calling opt, but it may be that opt breaks them.

Reproduce the crash with llvm-as on test/programs/llvm/nucleic.ll using the command shown. Start at Verifier::visitIntrinsicCall and inspect the llvm.experimental.gc.statepoint.p0 call and the related constants. Done means the reproducer no longer crashes in the verifier and the reported input is handled correctly.
