Alexandros Lamprineas 20e9ddba73 [ARM] Fix invalid VLDM/VSTM access when targeting Big Endian with NEON
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.

George Rimar e4dce5ce3e [Object/ELF] - Do not crash on invalid Header->e_shoff value.
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.

Michael Zuckerman 3eeac2d56b [x86][inline-asm][llvm] accept 'v' constraint
Commit in the name of:Coby Tayree
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)

Brian Gesiak 11c48475c4 [lit] Remove (or allow specific) unused imports
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.

Elena Demikhovsky 5b10aa1f1e DAG: Setting Masked-Expand-Load as a variant of Masked-Load node
Masked-expand-load node represents load operation that loads a variable amount of elements from memory according to amount of "true" bits in the mask and expands the loaded elements according to their position in the mask vector.
Right now, the node is used in intrinsics for VEXPAND* instructions. 
The work is done towards implementation of masked.expandload and masked.compressstore intrinsics.
