1f8008cf21 fix MCSectionELF to not leak memory, just like I did for MCSymbol. 
MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

42263e2e40 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.

3192d14076 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.

cebae36f57 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.

09d53fecfc move three lowering hooks from MAI to TLOF and make one of them 
semantic instead of syntactic.  This completes MCization of
darwin/x86[-64]!

98cdab53c3 set the temporary bit on MCSymbols correctly.

314fef6127 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).

d556155afd Okay. One last attempt: 
Place the LSDA into the TEXT section on Mach-O. This saves space.

293d592bf9 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.

6b89aa57e6 Revert Anton's most recent EH patch (r96637), since it breaks a lot of 
ARM and Thumb tests.

f0e7c87e56 Use the same encoding for EH stuff uniformly on all MachO targets. 
This hopefulyl should unbreak EH on PPC/Darwin.
