wrap-up (e.g., turning tentative definitions into definitions). Also,
very that, when we actually use the PCH file, we get the ride code
generation for tentative definitions and definitions that show up in
the PCH file.

This fixes <rdar://problem/6782722> XCDataTipsManager.m registers, observes notifications in class methods.
The radar above is the result of clang typing 'self' in a class method as 'Class', which results in some spurious warnings (GCC types 'self' in a class method as 'id').
I considered changing the type of 'self' to 'id' (to conform to GCC), however this resulted in *many* test cases breaking. In addition, I really prefer a more strongly typed 'self'.
All in all, this is the least obtrusive fix I could find for removing the spurious warnings (though we do loose some valid warnings).

- Pull out SetCommonAttributes, which handles the things common to
aliases, methods, functions, and variables.
- Pull out SetLLVMFunctionAttributesForDefinition, which handles the
LLVM attributes which we only want to apply to a definition (like
noinline and alwaysinline).
- Kill SetGVDeclarationAttributes (inlined into SetFunctionAttributes
and specialized).
- Kill SetFunctionAttributesForDefinition (inlined into sole caller).
- Inline SetGVDefinitionAttributes into SetMethodAttributes and
specialize.
- Rename SetGVDefinitionAttributes to SetFunctionDefinitionAttributes.
This is supposed to be a no functionality change commit, but I may
have made a mistake.

Don't do this in strict-C89 mode because bcpl comments aren't
valid there, and it is too much trouble to analyze whether
C block comments are safe.

- Exposed quite a few Sema issues and a CodeGen crash.
- See FIXMEs in test case, and in SemaDecl.cpp (PR3983).
I'm skeptical that __private_extern__ should actually be a storage
class value. I think that __private_extern__ basically amounts to
extern A __attribute__((visibility("hidden")))
and would be better off handled (a) as that, or (b) with an extra bit
in the VarDecl.

non-inline external definitions (and tentative definitions) that are
found at the top level. The corresponding declarations are stored in a
record in the PCH file, so that they can be provided to the
ASTConsumer (via HandleTopLevelDecl) when the PCH file is read.

promoted to legal types without changing the type of the vector. This is
following a suggestion from Duncan
(http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-February/019923.html).
The transformation that used to be done during type legalization is now
postponed to DAG legalization. This allows the BUILD_VECTORs to be optimized
and potentially handled specially by target-specific code.
It turns out that this is also consistent with an optimization done by the
DAG combiner: a BUILD_VECTOR and INSERT_VECTOR_ELT may be combined by
replacing one of the BUILD_VECTOR operands with the newly inserted element;
but INSERT_VECTOR_ELT allows its scalar operand to be larger than the
element type, with any extra high bits being implicitly truncated. The
result is a BUILD_VECTOR where one of the operands has a type larger the
the vector element type.
Any code that operates on BUILD_VECTORs may now need to be aware of the
potential type discrepancy between the vector element type and the
BUILD_VECTOR operands. This patch updates all of the places that I could
find to handle that case.
