fc746c2268 BPRED: Fixed the treshold-bug in the tournament predictor.
Suppose the saturating counters of a branch predictor contain n bits.  When the
counter is between 0 and (2^(n-1) - 1), boundaries included, the branch is
predicted as not taken.  When the counter is between 2^(n-1) and (2^n - 1),
boundaries included, the branch is predicted as taken.

c4497dbf03 X86: Make the cvti2f microop sign extend its integer source correctly.
The code was using the wrong bit as the sign bit. Other similar bits of code
seem to be correct.

f07ee128cc compile: don't #include unnecessary stuff
Time from base/time.hh has a name clash with Time from Ruby's
TypeDefines.hh.  Eventually Ruby's Time should go away, so instead of
fixing this properly just try to avoid the clash.

51a3d65e25 X86: Finally fix a division corner case.
When doing an unsigned 64 bit division with a divisor that has its most
significant bit set, the division code would spill a bit off of the end of a
uint64_t trying to shift the dividend into position. This change adds code
that handles that case specially by purposefully letting it spill and then
going ahead assuming there was a 65th one bit.

4225a68a95 scons: don't maintain files in sorted order
This causes builds to happen in sorted order rather than in
declaration order. This gets annoying when you make a global change
and then you notice that the files that are being compiled are jumping
around the directory hierarchy.

b49511ae48 inorder: timing for inst forwarding
when insts execute, they mark the time they finish to be used for subsequent isnts
they may need forwarding of data. However, the regdepmap was using the wrong
value to index into the destination operands of the instruction to be forwarded.
Thus, in some cases, we are checking to see if the 3rd destination register
for an instruction is executed at a certain time, when there is only 1 dest. register
valid. Thus, we get a bad, uninitialized time value that will stall forwarding
causing performance loss but still the correct execution.

f32674d9bc eventq: Clean up some flags
- Make the initialized flag always available, not just in debug mode.
- Make the Initialized flag actually use several bits so it is very
unlikely that something that's uninitialized accidentally looks
initialized.
- Add an initialized() function that tells you if the current event is
indeed  initialized.
- Clear the flags on delete so it can't be accidentally thought of as
initialized.
- Fix getFlags assert statement.  "How did this ever work?"

2ee3edba8e eventq: Make priorities just an integer instead of an enum.
Symbolic names should still be used, but this makes it easier to do
things like:
Event::Priority MyObject_Pri = Event::Default_Pri + 1

Remember that higher numbers are lower priority (should we fix this?)

01dffaa32f refcnt: no default copy contructor or copy operator
We shouldn't allow these because the default versions will copy
the reference count which is definitely not what we want.

f1c3f3044b ruby: get "using namespace" out of headers
In addition to obvious changes, this required a slight change to the slicc
grammar to allow types with :: in them.  Otherwise slicc barfs on std::string
which we need for the headers that slicc generates.

f066bfc2f5 cpu: get rid of uncached access "events"
These recordEvent() calls could cause crashes since they
access the req pointer after it's potentially been
deleted during a failed translation call.  (Similar
problem to the traceData bug fixed in the previous cset.)

Moving them above the translation call (as was done
recentlyi in cset 8b2b8e5e7d35) avoids the crash
but doesn't work, since at that point we don't know if
the access is uncached or not.

It's not clear why these calls are there, and no one
seems to use them, so we'll just delete them.  If they
are needed, they should be moved to somewhere that's
guaranteed to be after the translation completes but
before the request is possibly deleted, e.g., in
finishTranslation().

4d77ea7a57 cpu: fix exec tracing memory corruption bug
Accessing traceData (to call setAddress() and/or setData())
after initiating a timing translation was causing crashes,
since a failed translation could delete the traceData
object before returning.

It turns out that there was never a need to access traceData
after initiating the translation, as the traced data was
always available earlier; this ordering was merely
historical.  Furthermore, traceData->setAddress() and
traceData->setData() were being called both from the CPU
model and the ISA definition, often redundantly.

This patch standardizes all setAddress and setData calls
for memory instructions to be in the CPU models and not
in the ISA definition.  It also moves those calls above
the translation calls to eliminate the crashes.
