Tobias Tebbi 392078fb83 Reland "[turbofan] extend type asserts to cover all JS types" 
This is a reland of 45227ffdb4
Differences:
- Handle one more flags conflict in variants.py.
- Disallow %VerifyType without --concurrent-recompilation.

Original change's description:
> [turbofan] extend type asserts to cover all JS types
>
> Extend type assertions to all types covering JavaScript values.
> This is achieved by allocating type representations on the heap using
> newly defined HeapObject subclasses. To allocate these in the compiler,
> we disable concurrent compilation for the --assert-types flag for now.
>
> Fix two type errors that came up with the existing tests:
> 1. JSCreateKeyValueArray has type Array (i.e., a JSArray) instead of
>    OtherObject.
> 2. OperationTyper::NumberToString(Type) can type the result as the
>    HeapConstant Factory::zero_string(). However, NumberToString does
>    not always produce this string. To avoid regressions, the CL keeps
>    the HeapConstant type and changes the runtime and builtin code to
>    always produce the canonical "0" string.
>
> A few tests were failing because they check for truncations to work
> and prevent deoptimization. However, AssertType nodes destroy all
> truncations (which is by design), so these tests are incompatible
> and now disabled for the assert_types variant.
>
> Drive-by fix: a few minor Torque issues that came up.
