yonghong-song 5686786c55 [BPF] Fix BitCast Assertion with NonZero AddrSpace (#130722) 
Alexei reported a bpf selftest failure with recent llvm for bpf prog
file progs/arena_spin_lock.c. The failure only happens when clang is
built with cmake option LLVM_ENABLE_ASSERTIONS=ON.

The error message looks like:
```
 clang: /home/yhs/work/yhs/llvm-project/llvm/lib/IR/Instructions.cpp:3460:
   llvm::BitCastInst::BitCastInst(Value *, Type *, const Twine &, InsertPosition):
   Assertion `castIsValid(getOpcode(), S, Ty) && "Illegal BitCast"' failed.
```
Further investigation shows that the problem is triggered in
  BPF/BPFAbstractMemberAccess.cpp
for code
```
  auto *BCInst =
      new BitCastInst(Base, PointerType::getUnqual(BB->getContext()));
```
For the above BitCastInst, Since 'Base' has non-zero AddrSapce, the
compiler expects the type also has the same AddrSpace. But the above
PointerType::getUnqual(...) does not have AddrSpace and hence causes the
assertion failure.

Providing the proper AddrSpace for the BitCast type fixed the issue.
