llvm::cl already has a function called llvm::apply() so this is
causing an ODR violation. The STLExtras version should win the
vote on which one gets to be called apply() since it is named
after the equivalent STL function, but since renaiming the cl
version is more difficult, let's do this for now to get the
bots green.

Without this, the following statements will create ArrayRefs that
refer to temporary storage that goes out of scope by the end of the
line:
someArrayRef = getSingleElement();
someArrayRef = {elem1, elem2};
Note that the constructor still has this problem:
ArrayRef<Element> someArrayRef = getSingleElement();
ArrayRef<Element> someArrayRef = {elem1, elem2};
but that's a little harder to get rid of because we want to be able to
use this in calls:
takesArrayRef(getSingleElement());
takesArrayRef({elem1, elem2});

This is equivalent to the C++14 std::apply(). Since we are not
using C++14 yet, this allows us to still make use of apply anyway.

The instructions VLDM/VSTM can only access word-aligned memory
locations and produce alignment fault if the condition is not met.
The compiler currently generates VLDM/VSTM for v2f64 load/store
regardless the alignment of the memory access. Instead, if a v2f64
load/store is not word-aligned, the compiler should generate
VLD1/VST1. For each non double-word-aligned VLD1/VST1, a VREV
instruction should be generated when targeting Big Endian.

Sometimes the very first PT_LOAD segment, created by lld, can be empty.
This happens when (all conditions met):
- Linker script is used
- First section in ELF image is not RO
- Not enough space for program headers.

Summary:
Once a base class has been made invalid (by a static_assert for example) all using-member declarations in the derived classes will result in a "not a base class" diagnostic. This diagnostic is very misleading and should not be emitted.
This change is needed to help libc++ produce reasonable diagnostics in `std::optional` and `std::variant`.
