cfdf2419bc Second half of a fix for PR218 & test/Regression/Assembler/2004-02-01-NegativeZero.llx. 
Basically we store floating point values as their integral components, instead of relying
on the semantics of floating point < to differentiate between values.  This is likely to
make the map search be faster anyway.

04667297af Change weight array into a vector and make it as big as the number of 
registers (not as the max number of registers).

Change toSpill from a std::set into a std::vector<bool>.

Use the reverse iterator adapter to do a reverse scan of allocatable
registers.

97017de187 Optimize liveAt() and overlaps(). We now use a binary search instead 
of a linear search to find the first range for comparisons. This cuts
down the linear scan register allocator running time by a factor of 3
in 254.perlbmk and by a factor of 2.2 in 176.gcc.
