Improves parsing and semantic analysis for MS __declspec attributes.  This includes support for the align (which fixes PR12631).

I've also removed the duplicate check for PARSED_ATTR since it seems
unnecessary, and would have made the code more complicated.

[TSan] Add a comment that tsan_flags.h may be included in the user code, and therefore shouldn't include other headers from TSan or common sanitizer runtime. User may need tsan_flags.h to provide its implementation of __tsan::OverrideFlags

[Sanitizer] State that sanitizer_libc.h header can be included in the user code (and therefore it shouldn't include other sanitizer runtime headers).

Note that this is mostly a structural patch that handles the change from the old
spelling style to the new one. One consequence of this is that all AT_foo_bar
enum values have changed to not be based off of the first spelling, but rather
off of the class name, so they are now AT_FooBar and the like (a straw poll on
IRC showed support for this). Apologies for code churn.

Most attributes have GNU spellings as a temporary solution until everything else
is sorted out (such as a Keyword spelling, which I intend to add if someone else
doesn't beat me to it). This is definitely a WIP.

I've also killed BaseCheckAttr since it was unused, and I had to go through
every attribute anyway.

It turns out SourceManager treating the "one-past-the-end" location as invalid,
but then failing to set the invalid flag properly.

option. On the driver, check if we are using libraries from gcc 4.7 or newer
and if so pass -fuse-init-array to the frontend.
The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in
.ctors, so we have to use .init_array.

TargetLoweringObjectFileELF. Use this to support it on X86. Unlike ARM,
on X86 it is not easy to find out if .init_array should be used or not, so
the decision is made via TargetOptions and defaults to off.

Add a command line option to llc that enables it.

because it expects a reference and receives a non-l-value.

For example, given:

  int foo(int &);
  template<int x> void b() { foo(x); }

clang will now print "expects an l-value for 1st argument" instead of
"no known conversion from 'int' to 'int &' for 1st argument". The change
in wording (and associated code to detect the case) was prompted by
comment #5 in PR3104, and should be the last bit of work needed for the
bug.

the compiler predefines buffer.  These are essentially part of
the Objective-C language.

Per post-commit review, it's not appropriate to use ExtWarn in C++, because
we can't prove that the inline function will actually be defined in more than
one place (and thus we can't prove that this violates the ODR).

This removes the warning entirely from uses in the main source file in C++.

revert r158660, since Chris has some issues with this patch (namely using code to reprent information only used by the compiler)

Original commit msg:
add the 'alloc' metadata node to represent the size of offset of buffers pointed to by pointers.
This metadata can be attached to any instruction returning a pointer

This includes treating anonymous namespaces like internal linkage, and allowing
const variables to be used even if internal. The whole thing's been broken out
into a separate function to avoid nested ifs.

diag-build acts as a wrapper for 'diagtool show-enabled', in the same way
that scan-build acts as a wrapper for the static analyzer. The common case is
simple: use 'diag-build make' or 'diag-build xcodebuild' to list the warnings
enabled for the first compilation command we see. Other build systems require
you to manually specify "dry-run" and "use $CC and $CXX"; if there is a build
system you are interested in, please add it to the switch statement.

diag-build is fairly stupid right now, but it serves its basic purpose.
Hopefully it can grow to meet any additional requirements.
