The backend string is only verified when available as it's possible to run
clang IRGen for targets that haven't been built or don't exist in LLVM.

DiagIDs are a cached resource generally only constructed from compile-time
constant or stable format strings.
Escaping arbitrary messages and constructing DiagIDs from them didn't make
sense.

This matches llc's behavior.
Before this patch clang would create a TargetInfo base on -triple but a llvm
CodeGen based on the triple in the module.

This simplifies the core benefit of -flimit-debug-info by taking a more
systematic approach to avoid emitting debug info definitions for types
that only require declarations. The previous ad-hoc approach (3 cases
removed in this patch) had many holes.
The general approach (adding a bit to TagDecl and callback through
ASTConsumer) has been discussed with Richard Smith - though always open
to revision.

Summary:
Most of this change is wiring the pragma all the way through from the
lexer, parser, and sema to codegen. I considered adding a Decl AST node
for this, but it seemed too heavyweight.
Mach-O already uses a metadata flag called "Linker Options" to do this
kind of auto-linking. This change follows that pattern.
LLVM knows how to forward the "Linker Options" metadata into the COFF
.drectve section where these flags belong. ELF support is not
implemented, but possible.
This is related to auto-linking, which is http://llvm.org/PR13016.

The code generation stuff is going to set attributes on the functions it
generates. To do that it needs the target options. Pass them through.

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.

token. This is important because the first token could actually be
after an #include that triggers a module import, which might use
either Sema or the AST consumer before it would have been initialized.

% is a common character in IR so we'd crash on almost any malformed IR. The
diagnostic formatter expects a formatting directive when it sees an unescaped %.

In the included testcase, soma thinks that we already have a definition after we
see the out of line decl. Codegen puts it in a deferred list, to be output if
a use is seen. This would break when we saw an explicit template instantiation
definition, since codegen would not be notified.
This patch adds a method to the consumer interface so that soma can notify
codegen that this decl is now required.

commit 149470. This fixes test/CodeGen/PR3589-freestanding-libcalls.c.
Original log:
ConstantArray::get() (for strings) is going away, use
ConstantDataArray::getString instead.
Many instances of ConstantArray::get() could be moved to
use more efficient ConstantDataArray methods that avoid a ton
of intermediate Constant*'s for each element (e.g.
GetConstantArrayFromStringLiteral). I don't plan on doing this
in the short-term though.

library, since modules cut across all of the libraries. Rename
serialization::Module to serialization::ModuleFile to side-step the
annoying naming conflict. Prune a bunch of ModuleMap.h includes that
are no longer needed (most files only needed the Module type).
