b27c523449 It makes no sense to have a ODR version of common 
linkage, so remove it.

8d01b15f19 ARM target now also recognize triplets like thumbv6-apple-darwin and set thumb mode and arch subversion. Eventually thumb triplets will go way and replaced with function notes.

5ab54d488f Introduce new linkage types linkonce_odr, weak_odr, common_odr 
and extern_weak_odr.  These are the same as the non-odr versions,
except that they indicate that the global will only be overridden
by an *equivalent* global.  In C, a function with weak linkage can
be overridden by a function which behaves completely differently.
This means that IP passes have to skip weak functions, since any
deductions made from the function definition might be wrong, since
the definition could be replaced by something completely different
at link time.   This is not allowed in C++, thanks to the ODR
(One-Definition-Rule): if a function is replaced by another at
link-time, then the new function must be the same as the original
function.  If a language knows that a function or other global can
only be overridden by an equivalent global, it can give it the
weak_odr linkage type, and the optimizers will understand that it
is alright to make deductions based on the function body.  The
code generators on the other hand map weak and weak_odr linkage
to the same thing.

9d4eb136da Overhaul my earlier submission due to feedback. It's a large patch, but most of 
them are generic changes.

- Use the "fast" flag that's already being passed into the asm printers instead
  of shoving it into the DwarfWriter.

- Instead of calling "MI->getParent()->getParent()" for every MI, set the
  machine function when calling "runOnMachineFunction" in the asm printers.

9dc1507838 Turns out AnalyzeBranch can modify the mbb being analyzed. This is a nasty 
suprise to some callers, e.g. register coalescer. For now, add an parameter
that tells AnalyzeBranch whether it's safe to modify the mbb. A better
solution is out there, but I don't have time to deal with it right now.

a259483aae Get rid of the last non-DebugLoc versions of getNode! 
Many targets build placeholder nodes for special operands, e.g.
GlobalBaseReg on X86 and PPC for the PIC base.  There's no
sensible way to associate debug info with these.  I've left
them built with getNode calls with explicit DebugLoc::getUnknownLoc operands. 
I'm not too happy about this but don't see a good improvement;
I considered adding a getPseudoOperand or something, but it
seems to me that'll just make it harder to read.

6fcee67989 Move a few containers out of ScheduleDAGInstrs::BuildSchedGraph 
and into the ScheduleDAGInstrs class, so that they don't get
destructed and re-constructed for each block. This fixes a
compile-time hot spot in the post-pass scheduler.

To help facilitate this, tidy and do some minor reorganization
in the scheduler constructor functions.

1b795803dd Re-did 60519. It turns out Darwin's handling of hidden visibility symbols are a bit more complicate than I expected. Both declarations and weak definitions still need a stub indirection. However, the stubs are in data section and they contain the addresses of the actual symbols.
