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.

c4057a13f1 macos: MacOS has deprecated getdirentries, so just disable the code. 
Hopefully it isn't used much

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.
