tentative definitions off to the ASTConsumer at the end of the
translation unit.
Eliminate CodeGen's internal tracking of tentative definitions, and
instead hook into ASTConsumer::CompleteTentativeDefinition. Also,
tweak the definition-deferal logic for C++, where there are no
tentative definitions.
Fixes <rdar://problem/6808352>, and will make it much easier for
precompiled headers to cope with tentative definitions in the future.

- PR3980.
- <rdar://problem/6762287> [irgen] crash when generating tentative
definition of incomplete structure
- This also avoids creating common definitions for things which are
later overwritten.
- XFAIL'ed external-defs.c, it isn't completing types properly yet.

- 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.

functionality, fixing a crash on the attached testcase. Eliminate the
BuiltinFunctions cache, as it can contain dangling pointers. This fixes
a bunch of valgrind errors on test/CodeGen/builtins.c

CodeGenModule::CreateRuntimeVariable.
- No real functionality change; although we now assert on silly
things like:
--
int objc_exception_throw;
void f0() { @throw(@"A"); }
--
instead of accepting it.

BlockModule. No functionality change. This should help people that
don't want to know anything about blocks not be confused by the
overloaded use of the term block or nor want to see all the blocks
goop.

we ensure that things added to the module can be found even when they
are not in GlobalDeclMap. The later is for increased flexibility,
should someone want to do something tricky like extern "Ada" in the
same module.

IRgen no longer relies on isConstantInitializer, instead we just try
to emit the constant. If that fails then in C we emit an error
unsupported (this occurs when Sema accepted something that it doesn't
know how to fold, and IRgen doesn't know how to emit) and in C++ we
emit a guarded initializer.
This ends up handling a few more cases, because IRgen was actually
able to emit some of the constants Sema accepts but can't Evaluate().
For example, PR3398.
