Minimal reverting of Issue 1824 - Object not const correct

[9rnsr]

This is an alternative pull of #277, keeping const qualifiers of TypeInfo classes.

dmd: dlang/dmd#1053
druntime: #278 (old)
phobos: dlang/phobos#702 (old)

This needs to be rebased. It can't be merged as-is.

[9rnsr]

OK. I rebased the branch, and now it can be automatically merged.

All three of these pull requests are failing the pull tester right now. Do they all have to be merged at once in order to build correctly? They seem okay from what I can tell, but I only have commit permissions for druntime and Phobos, so if all 3 need to be merged at once, someone else is going to have to do it.

Yes. The three pulls require each other to avoid failing tests.

Then, I will merge these on your behalf. OK?

The change looks OK to me too.
The const-covariant TypeInfo.toString override is also fine for now.
I haven't checked for completeness though.

Then, I will merge these on your behalf. OK?

Please do.

Alright, this is great. Again std.xml is the remaining problem. @9rsr, please advise. Thanks!

[andralex]

Done!!!
