This commit prepares for the introduction of float support to Winch. Initially, I intended to include this change as part of the original change supporting floats, but that change is already sizable enough.
This modification simplifies the Assembler and MacroAssembler interfaces, as well as the interaction and responsibilities between them, by:
Eliminating the
Operandabstraction, which didn't offer a substantial benefit over simply using the MacroAssembler'sRegImmandAddressabstractions as operands where necessary. This approach also reduces the number of conversions required prior to emission.Shifting the instruction dispatch responsibility solely to the MacroAssembler, rather than having this responsibility shared across both abstractions. This was always the original intention behind the MacroAssembler. As a result, function definitions at the Assembler layer become simpler.
This change also introduces richer type information for immediates, which results in better instruction selection in some cases, and it's also needed to support floats.
