There is a fundemental flaw in how unaligned accesses are supported, but this

fc6b2cceb4 X86: Make fixed register operands ignore register index extensions from the REX prefix.
The only cases where this was the correct behavior are now handled with the
"B" operand type, and doing things this way was breaking some instructions,
notably a shift.

0e6be2a9b1 X86: Add the arch_prctl system call and fix up some microcoding.
The arch_prctl system call is used to set and get the FS and GS segment
bases. The FS segment is use for TLS, so glibc needs to be able to set it
up.

fae60c164e Arguments: Get rid of duplicate code for the Arguments class in each architecture.
Move the argument files to src/sim and add a utility.cc file with a function
getArguments() that returns the given argument in the architecture specific fashion.
getArguments() was getArg() is the architecture specific Argument class and has had
all magic numbers replaced with meaningful constants. Also add a function to the
Argument class for testing if an argument is NULL.

239d124e83 MIPS: Cleaned up includes to break loops, and got rid of isa_traits.cc
Loops of header files including each other was causing compilation to fail. To fix it, a bunch of unnecessary includes were removed, and the code in isa_traits.cc which brought a bunch of include chains together was broken up and put in proximity to the header files that delcared it.
