Tom Care b704270779 Added FixIt support to printf format string checking.
- Refactored LengthModifier to be a class.
- Added toString methods in all member classes of FormatSpecifier.
- FixIt suggestions keep user specified flags unless incorrect.

Limitations:
- The suggestions are not conversion specifier sensitive. For example, if we have a 'pad with zeroes' flag, and the correction is a string conversion specifier, we do not remove the flag. Clang will warn us on the next compilation.

Douglas Gregor 1fc3d66da4 Tweak our handling of the notion of a standard conversion sequence
being a subsequence of another standard conversion sequence. Instead
of requiring exact type equality for the second conversion step,
require type *similarity*, which is type equality with cv-qualifiers
removed at all levels. This appears to match the behavior of EDG and
VC++ (albeit not GCC), and feels more intuitive. Big thanks to John
for the line of reasoning that supports this change: since
cv-qualifiers are orthogonal to the second conversion step, we should
ignore them in the type comparison.

Daniel Dunbar 24e52992c0 Driver: Support invoking Clang on .ll or .bc inputs.
- We actually pretend that we have two separate types for LLVM assembly/bitcode because we need to use the standard suffixes with LTO ('clang -O4 -c t.c' should generate 't.o').

It is now possible to do something like:
  $ clang -emit-llvm -S t.c -o t.ll ... assorted other compile flags ...
  $ clang -c t.ll -o t.o ... assorted other compile flags ...
and expect that the output will be almost* identical to:
  $ clang -c t.c -o t.o ... assorted other compile flags ...
because all the target settings (default CPU, target features, etc.) will all be initialized properly by the driver/frontend.

*: This isn't perfect yet, because in practice we will end up running the optimization passes twice. It's possible to get something equivalent out with a well placed -mllvm -disable-llvm-optzns, but I'm still thinking about the cleanest way to solve this problem more generally.

Daniel Dunbar 6f8362c6bf Frontend: Add CodeGenAction support for handling LLVM IR.
- This magically enables using 'clang -cc1' as a replacement for most of 'llvm-as', 'llvm-dis', 'llc' and 'opt' functionality.

For example, 'llvm-as' is:
  $ clang -cc1 -emit-llvm-bc FOO.ll -o FOO.bc
and 'llvm-dis' is:
  $ clang -cc1 -emit-llvm    FOO.bc -o -
and 'opt' is, e.g.:
  $ clang -cc1 -emit-llvm -O3 -o FOO.opt.ll FOO.ll
and 'llc' is, e.g.:
  $ clang -cc1 -S -o - FOO.ll

The nice thing about using the backend tools this way is that they are guaranteed to exactly match how the compiler generates code (for example, setting the same backend options).

John McCall 75b960e5ee Alter the ExternalASTSource interface to permit by-name lookups. PCH continues to
bring in the entire lookup table at once.

Also, give ExternalSemaSource's vtable a home.  This is important because otherwise
any reference to it will cause RTTI to be emitted, and since clang is compiled
with -fno-rtti, that RTTI will contain unresolved references (to ExternalASTSource's
RTTI).  So this change makes it possible to subclass ExternalSemaSource from projects
compiled with RTTI, as long as the subclass's home is compiled with -fno-rtti.

of the postfix expr starts on a new line.  This should avoid

Daniel Dunbar eaff5fa30a Frontend: Sprinkle in some C++ header paths for ARM/Darwin. Also, don't add x86
paths on non-x86.

I really detest this file.

John McCall 4583186b8b When filtering out previous declarations of friend functions, consider the
lookup context, not the direct semantic context.  Fixes PR7230.

Douglas Gregor d37c59dae7 Don't put method bodies into code completions unless code patterns are
turned on.

Douglas Gregor 70febae768 Do not produce types as valid code completions when we're in an
expression context in C/Objective-C, or when we're in an
@interface/@implementation/@protocol in Objective-C(++).

Douglas Gregor f4c33349b5 Make -code-completion-patterns only cover multi-line code
completions. Plus, tweak a few completion patterns to better reflect
the language grammar.

Douglas Gregor a817a19bc6 Implement a code-completion hook for the receiver of an Objective-C
message. This completion gives better results than just using the
"expression" completion, which is effectively what happened before.

Douglas Gregor fd42e9542c Tweak the fix-it for a copy constructor declared to take its argument
by-value. We now only prepend a space if it is needed.
