There are two reasons why we might want to use
...
foo = a - b
.long foo
instead of just
.long a - b
First, on darwin9 64 bits the assembler produces the wrong result. Second,
if "a" is the end of the section all darwin assemblers (9, 10 and mc) will not
consider a - b to be a constant but will if the dummy foo is created.
Split how we handle these cases. The first one is something MC should take care
of. The second one has to be handled by the caller.

Make EmitIntValue more efficient and more like what we do for leb128. The

difference is much smaller (about 0.3s) but significant.

Do with uleb the same trick we now do with dwarf line/address advances. This

avoids creating leb128 fragments and speeds up the test in PR8711 to 33s.

Try to resolve symbol differences early, and if successful create a plain
...
data fragment. This reduces the time to assemble the test in 8711 from 60s to
54s.
