Bill Wendling 8594fcbd1a Make sure that the Attribute object represents one attribute only. 
Several places were still treating the Attribute object as respresenting
multiple attributes. Those places now use the AttributeSet to represent
multiple attributes.

Dmitri Gribenko 9feeef40f5 Move UTF conversion routines from clang/lib/Basic to llvm/lib/Support 
This is required to use them in TableGen.

Bill Wendling 290d952bb4 Use the AttributeSet instead of AttributeWithIndex. 
In the future, AttributeWithIndex won't be used anymore. Besides, it exposes the
internals of the AttributeSet to outside users, which isn't goodness.

John McCall 6bd2a89d5a The standard ARM C++ ABI dictates that inline functions are 
never key functions.  We did not implement that rule for the
iOS ABI, which was driven by what was implemented in gcc-4.2.
However, implement it now for other ARM-based platforms.

Bill Wendling ce2f9c5c63 Remove the last of uses that use the Attribute object as a collection of attributes. 
Collections of attributes are handled via the AttributeSet class now. This
finally frees us up to make significant changes to how attributes are structured.

Bill Wendling 9a6779294f Use the AttributeSet when adding multiple attributes and an Attribute::AttrKind 
when adding a single attribute to the function.

Bill Wendling b7abb30d77 Have AttributeSet::getRetAttributes() return an AttributeSet instead of Attribute. 
This further restricts the use of the Attribute class to the Attribute family of
classes.

Bill Wendling 304f6f0a59 Make AttributeSet::getFnAttributes() return an AttributeSet instead of an Attribute. 
This is more code to isolate the use of the Attribute class to that of just
holding one attribute instead of a collection of attributes.

Douglas Gregor bc25ff4661 Topologically sort the link options generated for modules based on 
module-import dependencies, so we'll get the link order correct for
those silly linkers that need it.

Douglas Gregor 1715a2f9d5 When forming the link options for an imported module, also include the 
link options for the modules it imports.

Douglas Gregor ea02f26536 Switch autolinking metadata format over to actual linker options, e.g., 
!0 = metadata !{metadata !"-lautolink"}
  !1 = metadata !{metadata !"-framework", metadata !"autolink_framework"}

referenced from llvm.module.linkoptions, e.g.,

  !llvm.module.linkoptions = !{!0, !1, !2, !3}

This conceptually moves the logic for figuring out the syntax the
linker will accept from LLVM into Clang. Moreover, it makes it easier
to support MSVC's

  #pragma comment(linker, "some option")

in the future, should anyone care to do so.

Douglas Gregor 6ddfca91e0 Implement parsing, AST, (de-)serialization, and placeholder global 
metadata for linking against the libraries/frameworks for imported
modules.

The module map language is extended with a new "link" directive that
specifies what library or framework to link against when a module is
imported, e.g.,

  link "clangAST"

or

  link framework "MyFramework"

Importing the corresponding module (or any of its submodules) will
eventually link against the named library/framework.

For now, I've added some placeholder global metadata that encodes the
imported libraries/frameworks, so that we can test that this
information gets through to the IR. The format of the data is still
under discussion.

Chandler Carruth ffd5551bc7 Rewrite #includes for llvm/Foo.h to llvm/IR/Foo.h as appropriate to 
reflect the migration in r171366.

Re-sort the #include lines to reflect the new paths.

Bill Wendling 5e85be4326 Remove the Function::getFnAttributes method in favor of using the AttributeSet 
directly.

This is in preparation for removing the use of the 'Attribute' class as a
collection of attributes. That will shift to the AttributeSet class instead.
