3b0f3b1ee2 ARM: Add a .w to the disassembly of 32 bit thumb instructions. 
This isn't technically correct since the .w should only be added if there are
32 and 16 bit encodings, but always having it always is better than never
having it.

c1aabe8172 style: clean up ruby's Set class 
Further cleanup should probably be done to make this class be non-Ruby
specific and put it in src/base.

There are probably several cases where this class is used, std::bitset
could be used instead.

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.
