448f49ee91 Revert "fix: reenable structure eta during tc search" 
The fix is blocked by slow defeq checks for TC instances; see issues
1986 and 2055.  Enabling it right now causes lots of timeouts in
mathlib4.
https://leanprover.zulipchat.com/#narrow/stream/287929-mathlib4/topic/bump.20to.202023-02-06/near/326223768

26edfc33f5 chore: remove unused isTaggedPtr from IR. 
This reduces the surface area of `unimplemented` in the LLVM backend,
and also removes dead code in the compiler.

fix: add done alternative to decreasing_with (#2019) 
Previously `decreasing_with` failed if `simp_wf` closes the goal on its
own. This can cause undesired regressions when new `simp` lemmas are
introduced.

Closes #2018.
