10f60fa411 Change RequiresMerge to RequiresUnique. It's a better description of what this 
fix is trying to accomplish.

This code could still use some polishing.

cd8fe46d4b If the destination module all ready has a copy of the global coming from the 
source module *and* it must be merged (instead of simply replaced or appended
to), then merge instead of replacing or adding another global.

The ObjC __image_info section was being appended to because of this
failure. This caused a crash because the linker expects the image info section
to be a specific size.

ca26f79051 Reapply r112091 and r111922, support for metadata linking, with a 
fix: add a flag to MapValue and friends which indicates whether
any module-level mappings are being made. In the common case of
inlining, no module-level mappings are needed, so MapValue doesn't
need to examine non-function-local metadata, which can be very
expensive in the case of a large module with really deep metadata
(e.g. a large C++ program compiled with -g).

This flag is a little awkward; perhaps eventually it can be moved
into the ClonedCodeInfo class.

a209503467 Use MapValue in the Linker instead of having a private function 
which does the same thing. This eliminates redundant code and
handles MDNodes better. MDNode linking still doesn't fully
work yet though.

1767723dbe Introducing the "linker_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. 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".

methods to try to have the type predicates be more logically positioned.

2c4a34aeef Fixed linking of modules containing aliases to constant bitcasts. Existing behaviour first tried to replace the aliases with the global that they aliased (rather than the bitcast), causing a crash on an assert because the types didn't match. When this was fixed, it then did the same thing creating the new alias (creating an alias with a different type to its aliasee). 
Linking modules containing aliases to GEPs is still not quite right.  GEPs that are equivalent to bitcasts will be replaced by bitcasts, GEPs that are not will just break.  Aliases to GEPs that are not equivalent to bitcasts are horribly broken anyway (it might be worth adding an assert when creating the alias to prevent these being created; they just cause problems later).

c521f54198 Prune #includes from llvm/Linker.h and llvm/System/Path.h, 
forcing them down into various .cpp files.

This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
   for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
   clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
   instead.
4. Weans llvm-db off <iostream>

sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.
