ModuleBuilder: assert that all deferred inline method defs get handled

While we're here, also move the declaration of DeferredInlineMethodDefinitions
closer to the other member vars and make it a SmallVector. NFC.

Revert "Change -save-temps to emit unoptimized bitcode files."

This reverts commit r224503.

It broke compilation of fortran through the Clang driver. Previously
`clang -c t.f` would invoke `gcc t.f` and `clang -cc1as`, but now it
tries to call `clang -cc1 t.f` which fails for obvious reasons.

Attributes accepting an EnumArgument are allowed to pass a string literal, or an identifier. VariadicEnumArguments now behave consistently instead of only accepting a string literal.

This change affects the only attribute accepting a variadic enumeration: callable_when.

Allow to disable all sanitizers with "-fno-sanitize=all" option.

Summary:
This patch adds "all" sanitizer group. A shortcut "-fno-sanitize=all"
can be used to disable all sanitizers for a given source file.

"-fsanitize=all" option makes no sense, and will produce an error.

This group can also be useful when we add "-fsanitize-recover=<list>"
options (patch in http://reviews.llvm.org/D6302), as it would allow
to conveniently enable/disable recovery for all specified sanitizers.

Tweak the assert in ModuleBuilder from r224533 (PR21989)

Turns out there will be left-over deferred inline methods if there have
been errors, because in that case HandleTopLevelDecl bails out early.

Don't drop attributes when checking explicit specializations.

Consider a template class with attributes on a method, and an explicit
specialization of that method:

    template <int>
    struct A {
      void foo() final;
    };

    template <>
    void A<0>::foo() {}

In this example, the attribute is `final`, but it might also be an
__attribute__((visibility("foo"))), noreturn, inline, etc. clang's current
behavior is to strip all attributes, which for some attributes is wrong
(the snippet above allows a subclass of A<0> to override the final method, for
example) and for others disagrees with gcc.

So stop dropping attributes. r95845 added this code without a test case, and
r176728 added the code for dropping attributes on parameters (with tests, but
they still pass).

As an additional wrinkle, do drop dllimport and dllexport, since that's how
these two attributes work. (This is covered by existing tests.)

Fixes PR21942.

The approach is by Richard Smith, initial analysis and typing was done by me.

With this, clang also matches GCC and EDG on all attributes Richard tested.
