[ubsan] Add support for -fsanitize-blacklist

llvm-svn: 172808

[IRgen] Update modules autolink metadata to use module flags (as now specified
in the LangRef).

llvm-svn: 172692

Add -fmodules-autolink/-fno-modules-autolink (defaults to on) so that
users can explicitly enable/disable modules autolinking.

Fix Const Cast

Do proper casting to avoid a cast-away-const error.

llvm-svn: 172559

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.

llvm-svn: 172459

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

Switch autolinking metadata format over to actual linker options, e.g.,

!0 = metadata !{metadata !"-lautolink"}

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.

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.

Remove the Function::getFnAttributes method in favor of using the AttributeSet

This is in preparation for removing the use of the 'Attribute' class as a

Revert r170500. It over-zealously converted *ALL* things named Attributes, which is wrong here.

Rename the 'Attributes' class to 'Attribute'. It's going to represent a single attribute in the future.

Rewrite calls to bitcast unprototyped functions when emitting a definition.

My variadics patch, r169588, changed these calls to typically be
bitcasts rather than calls to a supposedly variadic function.
This totally subverted a hack where we intentionally dropped
excess arguments from such calls in order to appease the inliner
and a "warning" from the optimizer. This patch extends the hack
to also work with bitcasts, as well as teaching it to rewrite
invokes.

Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.
