having to evaluate the expression again when writing.

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.

doing that if the target is darwin10 or newer.

This fixes
*) Direct object emission was producing objects without the workaround on
   darwin9.
*) Assembly printing was producing objects with the workaround on linux.

darwin9 linker, what is needed to avoid it and where to get more information.

Also make the workaround simpler. Just the regular end_sequence we normally
create is more than 4 bytes.

Tested by building cctools and ld64 from darwin9 on a darwin10 system and using
those. I checked that I was able to reproduce the bootstrap failure when
the the workaround was disabled.

It may not be an option to skip .debug_line if there are file reference in already emitted debug info. So, for now, emit dummy line table entry to make older linker and assemblers happy. This is not a new behavior, original AsmPrinter emitted similar line table entries.

This cuts the assembly time of the testcase in PR8711 from 2:50 minutes to 1

This moves a hack from the generic assembler to the elf writer. It is also
a bit faster and should make other improvements easier.
