3971df5203 Move unnamed_addr after the function arguments on Sabre's request.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124209 91177308-0d34-0410-b5e6-96231b3b80d8

bea4626f93 First step in fixing PR8927:
Add a unnamed_addr bit to global variables and functions. This will be used
to indicate that the address is not significant and therefore the constant
or function can be merged with others.

If an optimization pass can show that an address is not used, it can set this.

Examples of things that can have this set by the FE are globals created to
hold string literals and C++ constructors.

Adding unnamed_addr to a non-const global should have no effect unless
an optimization can transform that global into a constant.

Aliases are not allowed to have unnamed_addr since I couldn't figure
out any use for it.

91fb4070e5 reapply 112894:
Remove #uses comments from functions: they we're padded out to column 50
and were potentially confusing for externally visible functions.

going further, remove the "<i8**> [#uses=3]" comments entirely. They
add a lot of noise, confuse people about what the IR is, and don't add 
any particular value.  When the types are long it makes it really really
hard to read IR.

If someone is interested in this sort of thing, the right way to do this
is to implement an AsmAnnotationWriter that produces the same output, and
add a flag to llvm-dis (only) to produce this output.

55ae515f9d Create the new linker type "linker_private_weak_def_auto".
It's similar to "linker_private_weak", but it's known that the address of the
object is not taken. For instance, functions that had an inline definition, but
the compiler decided not to inline it. Note, unlike linker_private and
linker_private_weak, linker_private_weak_def_auto may have only default
visibility.  The symbols are removed by the linker from the final linked image
(executable or dynamic library).

5e721d7682 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.
