This reverts commit r283798, as it causes static asserts on
MSVC 2015 with the following errors:
ArrayRefTest.cpp(38): error C2338: Assigning from single prvalue element
ArrayRefTest.cpp(41): error C2338: Assigning from single xvalue element
ArrayRefTest.cpp(47): error C2338: Assigning from an initializer list

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});

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.

Fixed copy+paste vector alignment to correct for per-element scalar loads

sections_begin() may return unalignment pointer when Header->e_shoff isinvalid.
That may result in a crash in clients, for example we have one in LLD:
assert((PtrWord & ~PointerBitMask) == 0 &&
"Pointer is not sufficiently aligned");
fails when trying to push_back Elf_Shdr* (unaligned) into TinyPtrVector.
Patch forces check for alignment of Header->e_shoff.

1.'v' constraint for (x86) non-avx arch imitates the already implemented 'x' constraint, i.e. allows XMM{0-15} & YMM{0-15} depending on the apparent arch & mode (32/64).
2.for the avx512 arch it allows [X,Y,Z]MM{0-31} (mode dependent)
This patch applies the needed changes to clang

Summary:
Using Python linter flake8 on the utils/lit reveals several linter
warnings designated "F401: Unused import". Fix or silence these
warnings.
Some of these unused imports are legitimate, while some are part of lit's API.
For example, users of lit expect to be able to access `lit.formats.ShTest` in
their `lit.cfg`, despite the module hierarchy for that symbol actually being
`lit.formats.shtest.ShTest`. To silence linter errors for these lines,
include a "noqa" directive.

Summary:
`ArgumentError` is not defined by the Python standard library.
Executing this line of code would throw a exception, but not the
intended one. It would throw a `NameError` exception, since `ArgumentError`
is undefined.
Use `ValueError` instead, which is defined by the Python standard
library.

Summary:
Semicolons aren't necessary as statement terminators in Python, and
each of these uses are superfluous as they appear at the end of a line.
The convention is to not use semicolons where not needed, so remove them.
