This adds support for the /link option, which forwards
subsequent arguments to the linker.

The test for this will only work when targetting win32.
Since that's the only target where clang-cl makes sense,
use that target by default.

It doesn't make any sense to accept "..." in the argument to a C-style cast,

Anything that comes after -- is treated as an input file. This
used to be handled automagically by the option parsing library,
but after LLVM r188314, we should handle it ourselves.

No functionality change.

When a local extern declaration redeclares some other entity, the type of that
entity is merged with the prior type if the prior declaration is visible (in C)
or is declared in the same scope (in C++).

 - Make LookupRedeclarationWithLinkage actually work in C++, use it in the right
   set of cases, and make it track whether it found a shadowed declaration.
 - Track whether we found a declaration in the same scope (for C++) including
   across serialization and template instantiation.

One day soon, tooling::Replacements will be changed from being implemented as
an std::set to being implemented as an std::vector. Until then, some new code
using vectors of Replacements would enjoy having a version of
applyAllReplacements that takes a vector.

If a Replacment is contained within the conflict range being built, the

We used to decide whether to really vectorize depending on the optimization
level in PassManagerBuilder.

This patch moves this decision to the clang driver. We look at the optimization
level and whether the f(no-)vectorize is set and decide whether to vectorize.

This allows us to simplify the logic in PassManagerBuilder to just a check for
whether the vectorizer should run or not.

We now do the right thing for:
$ clang -O1 -fvectorize
$ clang -fno-vectorize -O3

Summary:
Refactor "MatcherList" into "VariantMatcher" and abstract the notion of a list of matchers for the polymorphic case.
This work is to support future changes needed for eachOf/allOf/anyOf matchers. We will add a new type on VariantMatcher.

Summary:
It seems that __uuidof introduces a global extern "C" declaration of
type __s_GUID.  However, our implementation of __uuidof does not provide
such a declaration and thus must open-code the mangling for __uuidof in
template parameters.

This allows us to codegen scoped COM pointers and other such things.

This fixes PR16836.
Depends on D1356.
