Continue the convergence between LLVM dialect and built-in types by using the built-in vector type whenever possible, that is for fixed vectors of built-in integers and built-in floats. LLVM dialect vector type is still in use for pointers, less frequent floating point types that do not have a built-in equivalent, and scalable vectors. However, the top-level `LLVMVectorType` class has been removed in favor of free functions capable of inspecting both built-in and LLVM dialect vector types: `LLVM::getVectorElementType`, `LLVM::getNumVectorElements` and `LLVM::getFixedVectorType`. Additional work is necessary to design an implemented the extensions to built-in types so as to remove the `LLVMFixedVectorType` entirely. Note that the default output format for the built-in vectors does not have whitespace around the `x` separator, e.g., `vector<4xf32>` as opposed to the LLVM dialect vector type format that does, e.g., `!llvm.vec<4 x fp128>`. This required changing the FileCheck patterns in several tests. Reviewed By: mehdi_amini, silvas Differential Revision: https://reviews.llvm.org/D94405
