Fixed x86 disassembler issues: 1) Corrected ModRMDecoder to use RegisterIndex.Sp instead of RegisterIndex.Si for SIB detection 2) Updated floating point instruction handlers to use proper instruction types 3) Enhanced ImmediateOperand.ToString() to show full 32-bit representation for sign-extended values
