now that means `llvm.assume`. The (transitive) uses are replaced by

Once we start the definition of an ObjCInterfaceDecl we won't attempt to ImportDeclContext
later on. Unlike RecordDecl case which uses DefinitionCompleter to force completeDefinition
we don't seem to have a similar mechanism for ObjCInterfaceDecl.
This fix was needed due to a bug we see in LLDB expression parsing where an initial expression
cause an ObjCInterfaceDecl to be defined and subsequent expressions during import do not call
ImportDeclContext and we can end up in a situation where ivars are imported out of order and not all ivars are imported.

Unfortunately this is another regression from my canonicalization patch
(1fed131660). The patch contained two implicit assumptions:
1. That we would have a permuted load only if we are loading a partial vector
2. That a partial vector load would necessarily be as wide as the splat
However, assumption 2 is not correct since it is possible to do a wider
load and only splat a half of it. This patch corrects this assumption by
simply checking if the load is permuted and adjusting the offset if it is.
Was accidentally squished into
rGb6cbe6cb0399d4671e5384dcc326af56bc6bd122. The assert fires on the code
snippet included in this commit.
More discussion can be found in https://reviews.llvm.org/D82598.
For comdats (e.g. caused by -ffunction-sections), Section is already
set here; make sure it's null, for the weak external symbol to be undefined.
This fixes PR46779.

When a process is notified that modules got loaded, currently only
existing language runtimes are given a chance to deal with that. This
means that if the runtime for a given language wasn't needed before it
won't be informed of the module chance.
This is wrong because the module change might be what triggers the need
for a certain runtime. Instead, we should give the language runtime for
every supported language a chance to deal with the modified modules.

ParseX86Triple already checks for 64-bit mode and produces a
static string. We can just add +sse2 to the end of that static
string. This avoids a potential reallocation when appending it
to the std::string at runtime.
This is a slight change to the behavior of tools that only use
MC layer which weren't implicitly enabling sse2 before, but will
now. I don't think we check for sse2 explicitly in any MC layer
components so this shouldn't matter in practice. And if it did
matter the new behavior is more correct.
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.

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>]

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.
