2017-03-08re-introduce __builtin_add_overflowshyouhei
r57789 (74cdd89) was gradually "improve"d by naruse through r57793 to r57806, resulted in reverting the efect of r57789 while retaining its complexity. I think the current situation is slightly worse than before (same output complicated source code). Here I introduce __builtin_add_overflow again, which (I think) is what naruse wanted to do in r57793. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57807 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-03-06optimize FIXABLE macroshyouhei
Looking at the source code, FIXABLE tends to be just before LOING2FIX to check applicability of that operation. Why not try computing first then check for overflow, which should be optimial. I also tried the same thing for unsigned types but resulted in slower execution. It seems RB_POSFIXABLE() is fast enough on modern CPUs. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57789 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-02-02Use carry flag to reduce instructionsnaruse
NOTE: (1) Fixnum's LSB is always 1. It means you can always run `x - 1` without overflow. (2) Of course `z = x + (y-1)` may overflow. Now z's LSB is always 1, and the MSB of true result is also 1. You can get true result in long as `(1<<63)|(z>>1)`, and it equals to `(z<<63)|(z>>1)` == `ror(z)`.
