Clean up signed/unsigned in vectorizer. Rationale: Currently we have some remaining ugliness around signed and unsigned SIMD operations due to lack of kUint32 and kUint64 in the HIR. By "softly" introducing these types, ABS/MIN/MAX/HALVING_ADD/SAD_ACCUMULATE operations can solely rely on the packed data types to distinguish between signed and unsigned operations. Cleaner, and also allows for some code removal in the current loop optimizer. Bug: 72709770 Test: test-art-host test-art-target Change-Id: I68e4cdfba325f622a7256adbe649735569cab2a3

ART: Introduce Uint8 compiler data type. This CL adds all the necessary codegen for the Uint8 type but does not add code transformations that use that code. Vectorization codegens are modified to use Uint8 as the packed type when appropriate. The side effects are now disconnected from the instruction's type after the graph has been built to allow changing HArrayGet/H*FieldGet/HVecLoad to use a type different from the underlying field or array. Note: HArrayGet for String.charAt() is modified to have no side effects whatsoever; Strings are immutable.

ART: Introduce compiler data type. Replace most uses of the runtime's Primitive in compiler with a new class DataType. This prepares for introducing new types, such as Uint8, that the runtime does not need to know about.
