objects and assembly

r122359 by rafael
Simplify EvaluateAsAbsolute now that EvaluateAsRelocatableImpl does all the
folding it can.

After this commit, debugging the program using GDB does not work anymore. 

GDB thinks all break points are near the end of the file, and so either don't
break where I put break points, or don't display informations about where it
stopped when I managed to tell it to break.

The generated asm is no affected by this commit, but the resulting objects are.

I attach an assembly file with generated objects before and after the commit.

They are compiled using the following command

> clang -arch i386 -c sync.s -o sync.o
