ce9a4ed124 Replace tfHasRequiresInit with a more accurate mechanism 
The new mechanism can deal with more complex scenarios such as
not nil field appearing in a non-default case object branch or
a field within a generic object that may depend on a when branch.

The commit also plugs another hole: the user is no longer able
to create illegal default values through seq.setLen(N).

Zahary Karadjov
0521f98486 Hrm, the new errors highlighted some code that seems to be broken 
New issue: since `Table[A, B]` allocates its backing storage with
`newSeq[KeyValuePair[A, B]]`, it's no longer legal to create a table
with `not nil` types used as either keys or values.

b1aa3b1eea Unwind just the "pseudorandom probing" part of recent sets,tables changes (#13816) 
* Unwind just the "pseudorandom probing" (whole hash-code-keyed variable
stride double hashing) part of recent sets & tables changes (which has
still been causing bugs over a month later (e.g., two days ago
https://github.com/nim-lang/Nim/issues/13794) as well as still having
several "figure this out" implementation question comments in them (see
just diffs of this PR).

This topic has been discussed in many places:
  https://github.com/nim-lang/Nim/issues/13393
  https://github.com/nim-lang/Nim/pull/13418
  https://github.com/nim-lang/Nim/pull/13440
  https://github.com/nim-lang/Nim/issues/13794

Alternative/non-mandatory stronger integer hashes (or vice-versa opt-in
identity hashes) are a better solution that is more general (no illusion
of one hard-coded sequence solving all problems) while retaining the
virtues of linear probing such as cache obliviousness and age-less tables
under delete-heavy workloads (still untested after a month of this change).

The only real solution for truly adversarial keys is a hash keyed off of
data unobservable to attackers.  That all fits better with a few families
of user-pluggable/define-switchable hashes which can be provided in a
separate PR more about `hashes.nim`.

This PR carefully preserves the better (but still hard coded!) probing
of the  `intsets` and other recent fixes like `move` annotations, hash
order invariant tests, `intsets.missingOrExcl` fixing, and the move of
`rightSize` into `hashcommon.nim`.

* Fix `data.len` -> `dataLen` problem.

e50441ab33 Fix typeSym.getImpl for ref types (#13752) 
* Fix typeSym.getImpl for ref types

* Fix a codegen issue affecting the test suite of nim-beacon-chain

* Fix tests/stdlib/tjsonmacro

To understand the fix better it may help to take a look
at the history of the replaced code.

The nil check that is removed in this commit was introduced
in another fix that failed to identify the root cause of the
issue - namely that we allow an object type to exist for which
no ast is present:

https://github.com/nim-lang/Nim/pull/9601/files

The original intention of the code is more obvious here:
