[mlir][Vector] Refactor VectorEmulateNarrowType.cpp (#123529)

This is PR refactors `alignedConversionPrecondition` from
VectorEmulateNarrowType.cpp and adds new helper hooks.

**Update `alignedConversionPrecondition` (1)**

This method doesn't require the vector type for the "container" argument. The
underlying element type is sufficient. The corresponding argument has been
renamed as `containerTy` - this is meant as the multi-byte container element
type (`i8`, `i16`, `i32`, etc). With this change, the updated invocations of
`alignedConversionPrecondition` (in e.g. `RewriteAlignedSubByteIntExt`) make it
clear that the container element type is assumed to be `i8`.

**Update alignedConversionPrecondition (2):**

The final check in `alignedConversionPrecondition` has been replaced with a new
helper method, `isSubByteVecFittable`. This helper hook is now also re-used in
`ConvertVectorTransferRead` (to improve code re-use).

**Other updates**

Extended + unified comments.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch
