This is in preparation for refactoring all x64::Inst arms to use OperandSize. Current uses of OperandSize fall into two categories: 1. XMM operations which require 32/64 bit operands 2. Immediates which only care about 64-bit or not. Adds assertions to existing Inst constructors to check that they are passed valid sizes. This change also removes the implicit widening of 1 and 2 byte values to 4 bytes. from_bytes() is only used by category 2, so removing this behavior will not change any visible behavior. Overall this change should be a no-op.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
