Remove the restriction that target intrinsics can only involve legal types.  Targets can perfects well support intrinsics on illegal types, as long as they are prepared to perform custom expansion during type legalization.  For example, a target where i64 is illegal might still support the i64 intrinsic operation using pairs of i32's.  ARM already does some expansions like this for non-intrinsic operations.

modules. This leaves us without an explicit syntax for importing
modules in C/C++, because such a syntax needs to be discussed
first. In Objective-C/Objective-C++, the @import syntax is used to
import modules.

Note that, under -fmodules, C/C++ programs can import modules via the
#include mechanism when a module map is in place for that header. This
allows us to work with modules in C/C++ without committing to a syntax.

The failure seen on win32, when i64 type is illegal.
It happens on stage of conversion VECTOR_SHUFFLE to BUILD_VECTOR.

The failure message is:
llc: SelectionDAG.cpp:784: void VerifyNodeCommon(llvm::SDNode*): Assertion `(I->getValueType() == EltVT || (EltVT.isInteger() && I->getValueType().isInteger() && EltVT.bitsLE(I->getValueType()))) && "Wrong operand type!"' failed.

I added a special test that checks vector shuffle on win32.

1.  Fix make_shared<const T>.  2.  Allow allocator<const T> as an extension.  3.  Refactor work which fixed unique_ptr<const T[]>.  4.  Remove no-longer-needed private declarations from unique_ptr.  5.  Add constraints to some shared_ptr and weak_ptr constructors and assignment operators so that is_constructible/is_assignable give the correct answers for shared_ptr and weak_ptr.  6.  Make defensive preparations in the shared_ptr free functions for the introduction of shared_ptr<T[]> in the future.  7.  As an optimization, add move constructor and move assignment to weak_ptr.
