Even though we're not incorrect about operator precedence, let's add
some parens in some particularly confusing places to placate GCC 4.3
so that we don't have to turn the warning off. Agreed that this is a
bit of a pain for those users who get the order of operations correct,
but it is likely to prevent bugs in certain cases.
Also some bug fixes in MIPS ISA uncovered by g++ warnings
(Python string compares don't work in C++!).

There is a fundemental flaw in how unaligned accesses are supported, but this
is still an improvement.

Merge was returning the value to merge in, not the actual result of the merge.

These functions take care of calling the thread contexts read and write functions with the right sized data type, and handle unaligned accesses.

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.

Some microops can set the condition codes, and some of them can be predicated on them. Some of the codes aren't implemented because it was unclear from the AMD patent what they actually did. They are used with string instructions, but they use variables IP, DTF, and SSTF which don't appear to be documented.
