2011-02-13	X86: Don't read in dest regs if all bits are replaced.	Gabe Black
	In x86, 32 and 64 bit writes to registers in which registers appear to be 32 or 64 bits wide overwrite all bits of the destination register. This change removes false dependencies in these cases where the previous value of a register doesn't need to be read to write a new value. New versions of most microops are created that have a "Big" suffix which simply overwrite their destination, and the right version to use is selected during microop allocation based on the selected data size. This does not change the performance of the O3 CPU model significantly, I assume because there are other false dependencies from the condition code bits in the flags register.

	This will reduce clutter in the source and hopefully speed up compilation.
2010-08-23	X86: Consolidate extra microop flags into one parameter.	Gabe Black
	This single parameter replaces the collection of bools that set up various flavors of microops. A flag parameter also allows other flags to be set like the serialize before/after flags, etc., without having to change the constructor.

2007-07-17	Make disassembled x86 register indices reflect their size.	Gabe Black
	This doesn't handle high byte register accesses. It also highlights the fact that address size isn't actually being calculated, and that the size a microop uses needs to be overridable from the microassembly. --HG-- extra : convert_revision : d495ac4f5756dc55a5f71953ff6963b3c030e6cb
