push GlobalDecl through enough of the CodeGenModule interfaces

to allow us to support generation of deferred ctors/dtors.
It looks like codegen isn't emitting a call to the dtor in
member-functions.cpp:test2, but when it does, its body should
get emitted.

Explictly track tentative definitions within Sema, then hand those
...
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.

noinline and alwaysinline).
- Kill SetGVDeclarationAttributes (inlined into SetFunctionAttributes
and specialized).
- Kill SetFunctionAttributesForDefinition (inlined into sole caller).
- Inline SetGVDefinitionAttributes into SetMethodAttributes and
