This is a grab bag of fallout changes from switching the VM to use LoweTEPass which can be ealy split out of the main apache#9483 PR. - AnnotateSpans can be used from C++ (though, unfortunately, it didn't help me with debugging since spans are universally dropped in most passes). - Can get a human readable dump of the VM's PackedFunc names and indexes for debugging. - If TVM_LOG_DEBUG defined then include types and ids of GlobalVars. I had a lot of difficulty tracking down where duplicate GlobalVars for the same name_hint were getting created and propagated. - GetCallLoweredProps follows same API as GetDeviceCopy and GetOnDevice where will return 'null' properties if call/expr is not of call_lowered form. Mildly more convenient, though switching all the above to ICHECK and push 'if (op == the relevant op)' into all use sites would also be just fine. - Misc VLOG improvements made while tracking down issues in apache#9483.

Can you clarify what exactly the return value is here given its just a std::string.

My I please do that in the sequel so we can merge and I take 9483 out of draft? These are just human readable pretty printed descriptions so I can decipher the instructions. Thx.

Given this is such a fundamental function it seems like we should have test cases for all the different cases it throws an exception and what we expect as a return value. Though I equally understand this wasn't authored in this PR.
@mbs-octoml / @electriclilies can you take a look at this?

Thanks @Mousius, agree and sorry I missed that in the orig PR. Can you take that @electriclilies ? Thanks!

where will return 'null' properties if call/expr is not of call_lowered
form. Mildly more convenient, though switching all the above to ICHECK
and push 'if (op == the relevant op)' into all use sites would also be just
fine and I can be talked into that too.
Targets and SEScopes are compared by pointer equality, and the same Target with
and without a host are distinct objects, this was causing unnecessary copies in code which
is already dealing with the explicit host_target or host_se_scope anyway. I've left the hosts
in the legacy_target_map. (The sooner we sort out multi-target compilation and hosts the
better!)
