Since yaml2obj is now able to parse integer values as relocation types,
there is no need to keep hex edited elf object for this test,
we can produce it on fly, just like this patch do.

Summary:
The std::move was preventing copy ellision when compiled with
clang, the patch fixes the warning along with rearranging code
to remove unused variables warnings on Linux machines with
older perf_event interface.

These all used 'CHECK-NOT' which isn't necessary if we have complete checks.
There were also several over-specifications in the RUN params such as CPU model or OS requirement

This reverts commit r306313. This breaks selfhost at -O3 and PR33652.

Changes are: replaced C-style casts with cons_cast and reinterpret_cast;
type of several counters changed to signed; type of parameters of 32-bit and
64-bit AND and OR intrinsics changes to unsigned; changed files formatted
using clang-format version 3.8.1.

This patch makes changes to allow sections without the SHF_ALLOC bit to be
assigned to segments in a linker script.
The assignment of output sections to segments is performed in
LinkerScript::createPhdrs. Previously, this function would bail as soon as it
encountered an output section which did not have the SHF_ALLOC bit set, thus
preventing any output section without SHF_ALLOC from being assigned to a
segment.
This restriction has now been removed from LinkerScript::createPhdrs and instead
a check for SHF_ALLOC has been added to LinkerScript::adjustSectionsAfterSorting
to not propagate program headers to sections without SHF_ALLOC which matches the
behaviour of bfd linker scripts.

We assumed the constant was a scalar when creating the replacement operand.
Also, improve tests for this fold and move the tests for this fold to their own file.
I'll move the related and missing tests to this file as a follow-up.

I noticed this missed bswap optimization in the CGP memcmp() expansion,
and then I saw that we don't have the fold in InstCombine.

We are combining shuffles to bit shifts before unary permutes, which means we can't fold loads plus the destination register is destructive

The 32-bit shuffles are a bit tricky and will be dealt with in a later patch

This is NFC after rerunning the "update_llc_test_checks.py" tool on the CodeGen X86 tests in order to submit a patch.
Minor differences due to added "End of Function" lines.
