Revert r149363 which was part a series of commits that were reverted in llvm
commit 149470. This fixes test/CodeGen/PR3589-freestanding-libcalls.c.

Original log:

ConstantArray::get() (for strings) is going away, use
ConstantDataArray::getString instead.

Many instances of ConstantArray::get() could be moved to
use more efficient ConstantDataArray methods that avoid a ton
of intermediate Constant*'s for each element (e.g.
GetConstantArrayFromStringLiteral). I don't plan on doing this
in the short-term though.

The following patch adds __attribute__((no_address_safety_analysis)) which will allow to disable
address safety analysis (such as e.g. AddressSanitizer or SAFECode) for a specific function.

When building with AddressSanitizer, add AddressSafety function attribute to every generated function
except for those that have __attribute__((no_address_safety_analysis)).

With this patch we will be able to
1. disable AddressSanitizer for a particular function
2. disable AddressSanitizer-hostile optimizations (such as some cases of load widening) when AddressSanitizer is on.

De-virtualize getPreviousDecl() and getMostRecentDecl() when we know
we have a redeclarable type, and only use the new virtual versions
(getPreviousDeclImpl() and getMostRecentDeclImpl()) when we don't have
that type information. This keeps us from penalizing users with strict
type information (and is the moral equivalent of a "final" method).

Plus, settle on the names getPreviousDecl() and getMostRecentDecl()
throughout.

constexpr irgen: Add irgen support for APValue::Struct, APValue::Union,
APValue::Array and APValue::MemberPointer. All APValue values can now be emitted
as constants.

Add new CGCXXABI entry point for emitting an APValue MemberPointer. The other
entrypoints dealing with constant member pointers are no longer necessary and
will be removed in a later change.

Switch codegen from using EvaluateAsRValue/EvaluateAsLValue to
VarDecl::evaluateValue. This performs caching and deals with the nasty cases in
C++11 where a non-const object's initializer can refer indirectly to
previously-initialized fields within the same object.

Building the intermediate APValue object incurs a measurable performance hit on
pathological testcases with huge initializer lists, so we continue to build IR
directly from the Expr nodes for array and record types outside of C++11.

The `-fwritable-strings' flag doesn't make the backing store strings of all
CFStrings writable.

The strings (both Unicode and ASCII) should reside in a read-only section. E.g.,
__TEXT,__cstring instead of __DATA,__data. This is done by making the global
variable created for the strings constant despite the value of that flag.
