4a7d0c4b79 bus: take out response prioritization (timing was messed up).
Also make express snoops not occupy bus (since they're magic).

362ff1bceb BsaeCPU: Get rid of some bad DPRINTFs.
People should never put pointers in DPRINTFs; it messes up
tracediffs.  Plus these used the FullCPU trace flag, which
is not right.

b4087e0e44 Statetrace: Make statetrace patch amd64 executables for true single stepping after system calls.
Because of peculiarities in how system calls are returned from, single stepping executes some system calls and the instruction following them in a single step. Statetrace now patches the executable image when it detects a system call to force "correct" behavior, aka the appearance of stepping one instruction every single time.

5e34c62b3b X86: Initial stack frame fixes and constant shuffling.
The initial stack frame for x86 is now substantially more correct. The fixes made here can be back ported to SPARC and possible the other ISAs as well. The auxiliary vector types were moved to the LiveProcess base class because they are independent of ISA. Some of the types may only apply to Linux, though, so they may have to be moved.

e996ff7497 X86: Fix up auxiliary vectors.
The type constants should go into an architecture independent spot since they are universal to all Linux elf binaries. The right value for some of the vectors needs to be determined. Also, x86 does not store argc or argv_array_base in registers like some other architectures.

d1e533a1e2 X86: Fix argument register indexing.
Code was assuming that all argument registers followed in order from ArgumentReg0. There is now an ArgumentReg array which is indexed to find the right index. There is a constant, NumArgumentRegs, which can be used to protect against using an invalid ArgumentReg.

The carry flag should be calculated using the -complement- of the second operand, not it's negation. The carry in which is part of computing the 2's complement may induce a carry, but if you've already caused the carry before you get the carry computing logic involved, it will miss it.
