Fix minor bugs and uses of undef which break when
pointer related optimization passes are run.

0638337d10 AMDGPU: Stop reporting an addressing mode for unknown addrspace
This was being treated the same as private, which has an immediate
offset. For unknown, it probably means it's for a computation not
actually being used for accessing memory, so it should not have a
nontrivial addressing mode.

4861e30522 LoopStrengthReduce: Try to pass address space to isLegalAddressingMode
This seems to only work some of the time. In some situations,
this seems to use a nonsensical type and isn't actually aware of the
memory being accessed. e.g. if branch condition is an icmp of a pointer,
it checks the addressing mode of i1.
