[analyzer] Track runtime types represented by Obj-C Class objects

Objective-C Class objects can be used to do a dynamic dispatch on
class methods. The analyzer had a few places where we tried to overcome
the dynamic nature of it and still guess the actual function that
is being called. That was done mostly using some simple heuristics
covering the most widespread cases (e.g. [[self class] classmethod]).
This solution introduces a way to track types represented by Class
objects and work with that instead of direct AST matching.

[MLIR] Introduce op trait PolyhedralScope (revised)

(A previous version of this, dd2c639c3cd397dfef941186fb85c82e4e918425, was

Introduce op trait PolyhedralScope for ops to define a new scope for
polyhedral optimization / affine dialect purposes, thus generalizing
such scopes beyond FuncOp. Ops to which this trait is attached will
define a new scope for the consideration of SSA values as valid symbols
for the purposes of polyhedral analysis and optimization. Update methods
that check for dim/symbol validity to work based on this trait.

[TTI] Add DemandedElts to getScalarizationOverhead

The improvements to the x86 vector insert/extract element costs in D74976 resulted in the estimated costs for vector initialization and scalarization increasing higher than should be expected. This is particularly noticeable on pre-SSE4 targets where the available of legal INSERT_VECTOR_ELT ops is more limited.

This patch does 2 things:
1 - it implements X86TTIImpl::getScalarizationOverhead to more accurately represent the typical costs of a ISD::BUILD_VECTOR pattern.
2 - it adds a DemandedElts mask to getScalarizationOverhead to permit the SLP's BoUpSLP::getGatherCost to be rewritten to use it directly instead of accumulating raw vector insertion costs.

This fixes PR45418 where a v4i8 (zext'd to v4i32) was no longer vectorizing.

A future patch should extend X86TTIImpl::getScalarizationOverhead to tweak the EXTRACT_VECTOR_ELT scalarization costs as well.
