671fa97a4b 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.

a779a9899a 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.

82482944ed TargetAsmInfo::getAddressSize() was incorrect for x86-64 and 64-bit targets
other than PPC64. Instead of fixing it, just remove it and fix all the
places that use it to use TargetData::getPointerSize() instead, as there
aren't very many. Most of the references were in DwarfWriter.cpp.

5032e5a613 * Fix one more bug in PIC codegen: extra load is needed for *all*
non-statics.
* Introduce new option to output zero-initialized data to .bss section.

Cygwin/Mingw targets. Probably, Darwin should be also added.
