[X86] Use X86_MC::ParseX86Triple to add mode features to feature string in X86Subtarget::initSubtargetFeatures.

Remove mode flags from constructor and remove calls to
ToggleFeature for the mode bits.

By adding them to the feature string we handle initializing the
mode member variables in X86Subtarget and the feature bits in
MCSubtargetInfo in one shot.

Added extra patterns to VABD instruction so it is selected in place of VSUB and VABS. Added corresponding regression test too.

Summary:
On 32-b, the release algo loops multiple times over the freelist for a size
class, which lead to a decrease in performance when there were a lot of free
blocks.

This changes the release functions to loop only once over the freelist, at the
cost of using a little bit more memory for the release process: instead of
working on one region at a time, we pass the whole memory area covered by all
the regions for a given size class, and work on sub-areas of `RegionSize` in
this large area. For 64-b, we just have 1 sub-area encompassing the whole
region. Of course, not all the sub-areas within that large memory area will
belong to the class id we are working on, but those will just be left untouched
(which will not add to the RSS during the release process).

Make sure we do not call
constainsConstantExpression/containsUndefElement on ConstantExpression,
which is not supported.

In particular, containsUndefElement/constainsConstantExpression are only
supported on constants which are supported by getAggregateElement.

Unfortunately there's no convenient way to check if a constant supports
getAggregateElement, so just check for non-constantexpressions with
vector type. Other users of those functions do so too.

Summary:
The resolver addresses stored in the dyld trie are relative to the base
of the __TEXT segment. This is usually 0 in a dylib, so this was never
noticed, but it is not 0 for most dylibs integrated in the shared cache.
As we started using the shared cache images recently as symbol source,
this causes LLDB to fail to resolve symbols which go through a runtime
resolver.

Currently supported LLVM MTBUF syntax is shown below. It is not compatible with SP3.

    op     dst, addr, rsrc, FORMAT, soffset

This change adds support for SP3 syntax:

    op     dst, addr, rsrc, soffset SP3FORMAT

In addition to being compatible with SP3, this syntax allows using symbolic names for data, numeric and unified formats. Below is a list of added syntax variants.

format:<expression>
format:[<numeric-format-name>,<data-format-name>]
format:[<data-format-name>,<numeric-format-name>]
format:[<data-format-name>]
format:[<numeric-format-name>]
format:[<unified-format-name>]

The last syntax variant is supported for GFX10 only.

Additionally fix the copy if enabled on multi-config targets.

Summary:
This changes the copy command for libomp.so to use the output of the target as
the source of the copy, rather than trying to find it based on
${LIBOMP_LIBRARY_DIR}, which appears to be incorrect in multi-config generator
builds.

This patch introduces conversion pattern for `spv.Store` and `spv.Load`.
Only op with `Function` Storage Class is supported at the moment
because `spv.GlobalVariable` has not been introduced yet. If the op
has memory access attribute, then there are the following cases.
If the access is `Aligned`, add alignment to the op builder. Otherwise
the conversion fails as other cases are not supported yet because they
require additional attributes for `llvm.store`/`llvm.load` ops: e.g.
`volatile` and `nontemporal`.

The patch introduces the conversion pattern for function-level
`spv.Variable`. It is modelled as `llvm.alloca` op. If initialized, then
additional store instruction is used. Note that there is no initialization
for arrays and structs since constants of these types are not supported in
LLVM dialect yet. Also, at the moment initialisation is only possible via
`spv.constant` (since `spv.GlobalVariable` conversion is not implemented
yet).

The input code has some scoping is not taken into account and will be
addressed in a different patch.

They were a part of D68983, but were lost in the last

I've renamed (from elf-sht-note.yaml) them and fixed
broken formating a few places. Everything else remained
untouched.

This concerns `from/to_extent_tensor`, `size_to_index`, `index_to_size`, and
`const_size` conversion patterns. The new lowering will work directly on indices
and extent tensors. The shape and size values will allow for error values but
are not yet supported by the dialect conversion.
