We don't seem to have any need for `TypeOf*Type` types, and having them introduces the temptation to use them during type-checking, which would lead to types having different behavior when their type-of-type is `Type` versus when it's a more precise type. Remove these types for now.
If we later decide that we want each type literal to have a unique type, as we do for value literals, we can introduce a single value kind for that rather than one for each kind of type.
No changes to `TypeOfMemberName`, `TypeOfParameterizedEntityName`, and `TypeOfMixinPseudoType`, which are placeholders, not real types.
Adds a simple script to merge stdout/stderr and put on labels. This is hidden to the RUN line using lit.cfg.py.
This is my solution to addressing how errors printed by the toolchain break sorting of stdout output; just put stdout first. We could also have toggles for interleaving output or such, which might help test whether we do it properly.
This also moves some previous-distributed replacement logic into lit_autoupdate_base.py: I think having that adjacent to lit.cfg.py is probably the better choice, and it reduces duplication in toolchain scripts. It happens here because I need to change the resulting commands to include the merge.
On #2224 @zygoloid pointed out we needed --implicit-check-not to ensure we were correctly matching output. This is the standard way we're writing explorer tests, so I was looking at unifying our lit approaches.
This is one take on it, making more use of substitutions to bring various testing into alignment, as well as symlinks to avoid config skew (maybe I'll eventually figure out a better solution than symlinks).
Makes a couple small fixes in explorer to remove end-of-line whitespace on output.
