Rip out the 'is temporary' nonsense from the MCContext interface to
...
create symbols. It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.
This fixes rdar://7807601.

fix MCSectionELF to not leak memory, just like I did for MCSymbol.
...
MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

fix a fixme in TargetLoweringObjectFile::getExprForDwarfReference
...
where we used ot create an MCSymbol for ".". Now emit an assembler
temporary label and reference it instead of "." textually.

rename getSymbolForDwarf* to getExprForDwarf* since it returns

an MCExpr and not an MCSymbol. Change it to take an MCStreamer,
which is currently unused.
No functionality change.

Add a bit along with the MCSymbols stored in the MachineModuleInfo maps that
...
indicates that an MCSymbol is external or not. (It's true if it's external.)
This will be used to specify the correct information to add to non-lazy
pointers. That will be explained further when this bit is used.

Don't emit global symbols into the (__TEXT,__ustring) section on Darwin. This
...
is a workaround for <rdar://problem/7672401/> (which I filed).
This let's us build Wine on Darwin, and it gets the Qt build there a little bit
further (so Doug says).

It turned out that we failed to emit proper symbol stubs on non-x86/darwin for ages (we emitted a reference to a stub, but no stub was emitted). The code inside x86-32/macho target objfile lowering should actually be the generic one - move it there.

This (I really, really hope) should fix EH issues on ppc/darwin
and arm/darwin.
