 I believe I managed to maintain the optimizations, even under DEBUG_IR
 (though there is additional overhead with new GlobalVariables, but not
 unlike the output of the AOT compiler).  At least those that stem from
 unbox_ruby_constant().  If there are other optimizations I missed, I can
 certainly take a look.

#521: Float problem with 8.1 and 9.1

 Actually, this should be fixed with the float changes in #159.  This
 problem stems from the last two bits of the floating point number being
 used as flags, so there is a lose in precision.  Worse is that in 32-bit
 mode, floating point is done with 32-bit floats, so the two bit lose in
 precision is even worse:

 {{{
 % macruby -e 'puts 8.1'
 8.09
 % arch -i386 macruby -e 'puts 8.1'
 8.0847412109
 }}}

 With the changes in #159:

 {{{
 % miniruby -e 'puts 8.1'
 8.1
 % arch -i386 miniruby -e 'puts 8.1'
 8.1
 }}}
