f21e2fe2b9 Make the "linker_private" linkage type emit a non-weak symbol to the file. It 
will still be stripped by the linker when it generates the final image.

17dc7d716b ARM function alignments were off by a power of two. svn 83242 changed 
getFunctionAlignment and the corresponding use of that value in the ARM
asm printer, but now we're using the standard asm printer.  The result of
this was that function alignments were dropped completely for Thumb functions.

90b6422f2f Implement the "linker_private_weak" linkage type. This will be used for 
Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.

For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:

      .globl l_objc_msgSend_fixup_alloc
      .weak_definition l_objc_msgSend_fixup_alloc
      .section __DATA, __objc_msgrefs, coalesced
      .align 3
l_objc_msgSend_fixup_alloc:
       .quad   _objc_msgSend_fixup
       .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

Currently only supported on Darwin platforms.

9e9393b767 evil hack to coerce external users (projects) 
to update their code to high-level interfaces

If you get compile errors in your project
please update your code according to the
comments.

This is a re-commit of r107396 which causes
compile errors for the indicated usage patterns
instead of link errors (which are less easy to
fix because of missing source location).

If you get compile errors please perform
following functionally equivalent transformations:
  - getOperand(0)  --->  getCalledValue()
  - setOperand(0, V)  --->  setCalledFunction(V)

This will make your code more future-proof
and avoid potentially hard-to-debug bugs.

please refer to this thread on llvm-dev:

a0fa700f3c Debugging infomration is encoded in llvm IR using metadata. This is designed 
such a way that debug info for symbols preserved even if symbols are
optimized away by the optimizer. 

Add new special pass to remove debug info for such symbols.
