Richard Smith d82a2ce3a0 Reinstate r170806, reverted in r170835, with a fix use i1 instead of i8 for a value-initialized bool!

Richard Smith fddd384b73 Unrevert r147271, reverted in r147361.
Also temporarily remove the assumption from IR gen that we can emit IR for every
constant we can fold, since it isn't currently true in C++11, to fix PR11676.

Original comment from r147271:

constexpr: perform zero-initialization prior to / instead of performing a
constructor call when appropriate. Thanks to Eli for spotting this.

John McCall f677a8e99e Convert the standard default-construction loops to use phis and
partial destruction.

John McCall 82fe67bb82 A number of array-related IR-gen cleanups.
- Emit default-initialization of arrays that were partially initialized
    with initializer lists with a loop, rather than emitting the default
    initializer N times;
  - support destroying VLAs of non-trivial type, although this is not
    yet exposed to users; and
  - support the partial destruction of arrays initialized with
    initializer lists when an initializer throws an exception.

Argyrios Kyrtzidis 03535265ef Cut down unnecessary zero'ing when value-initializing arrays of C++ objects.
-C++ objects with user-declared constructor don't need zero'ing.
-We can zero-initialize arrays of C++ objects in "bulk" now, in which case don't zero-initialize each object again.

Argyrios Kyrtzidis e07425a5e7 When value-initializing the elements of an array not not included in the initializer make sure
that a non-trivial C++ constructor gets called.

Douglas Gregor b0a04fff51 Preserve the zero-initialization and construction-kind settings when
instantiating CXXConstructExpr expressions.

Douglas Gregor 630c76efb0 When performing value-initialization for a class with a non-trivial,
implicitly-defined default constructor, zero-initialize the memory
before calling the default constructor. Previously, we would only
zero-initialize in the case of a trivial default constructor.

Also, simplify the hideous logic that determines when we have a
trivial default constructor and, therefore, don't need to emit any
call at all.

Douglas Gregor e3b3464d4e Fix a major regression with value-initialization of class types with
trivial default constructors. We're weren't zero-initializing them,
which manifested as <rdar://problem/8320532> (a regression in the GCC
test suite) and is likely to have caused significant other breakage.

John McCall 7cd1d97e33 Inline a special case of EmitAggregateCopy into EmitNullInitialization
to avoid the awesome-but-wrong-in-this-case assertion in the canon EAC.
Fixes PR7834.

Also fix a subtle address-space bug in the memset path.

Douglas Gregor 199db36b79 When explicitly building a temporary object (CXXTemporaryObjectExpr),
keep track of whether we need to zero-initialize storage prior to
calling its constructor. Previously, we were only tracking this when
implicitly constructing the object (a CXXConstructExpr).

Fixes Boost's value-initialization tests, which means that the
Boost.Config library now passes all of its tests.
