6add893a14 GCC doesn't emit DW_EH_PE_sdata4 for the FDE encoding on Darwin. I'm not sure
about other platforms.

1ed08a58d1 Fix logic for not emitting no-dead-strip for some
objects in llvm.used (thanks Anton).  Makes visible
the magic 'l' prefix for symbols on Darwin which are
to be passed through the assembler, then removed at
linktime (previously all references to this had been
hidden in the ObjC FE code, oh well).

aac5c915ed Linux also does not require exception handling
moves in order to get correct debug info.  Since
I can't imagine how any target could possibly
be any different, I've just stripped out the
option: now all the world's like Darwin!

6f4e916c6a Output correct exception handling and frame info
on x86-64 linux.  This causes no regressions on
32 bit linux and 32 bit ppc.  More tests pass
on 64 bit ppc with no regressions.  I didn't
turn on eh on 64 bit linux because the intrinsics
needed to compile the eh runtime aren't done
yet.  But if you turn it on and link with the
mainline runtime then eh seems to work fine
on x86-64 linux with this patch.  Thanks to
Dale for testing.  The main point of the patch
is that if you output that some object is
encoded using 4 bytes you had better not output
8 bytes for it: the patch makes everything
consistent.

c860d9c77c Add AsmPrinter support for emitting a directive to declare that
the code being generated does not require an executable stack.

Also, add target-specific code to make use of this on Linux
on x86.
