region with implicit default inside the member function.
This is to fix assert when field is referenced in OpenMP region with
default (first|private) clause inside member function.
The problem of assert is that the capture is not generated for the field.
This patch is to generate capture when the field is used with implicit
default, use it in the code, and save the capture off to make sure it is
considered from that point and add first/private clauses.
1> Add new field ImplicitDefaultFirstprivateFDs in SharingMapTy, used to
store generated capture fields info.
2> In function isOpenMPCaptureDecl: the caputer is generated and saved
in ImplicitDefaultFirstprivateFDs.
3> Add new help functions:
getImplicitFDCapExprDecl
isImplicitDefaultFirstprivateFD
addImplicitDefaultFirstprivateFD
4> Add addition argument in hasDSA to check default attribute for
default(first|private).
5> The isImplicitDefaultFirstprivateFD is used in VisitDeclRefExpr to
build the implicit clause.
6> Add new parameter "Context" for buildCaptureDecl, due to when capture
field, the parent context is needed to be used.
7> Change in isOpenMPPrivateDecl where stop propagate the capture from
the enclosing region for private variable.
8> In ActOnOpenMPFirstprivate/ActOnOpenMPPrivate, using captured info
to generate first|private clause.
9> Add new function isOpenMPRebuildMemberExpr: use to determine if field
needs to be rebuild during template instantiation.

If BOLT instrumentation runtime uses XMM registers, it can interfere
with the user program causing crashes and unexpected behavior. This
happens as the instrumentation code preserves general purpose registers
only.

This is a preprocessor callback focused on the lexed file changing, without conflating effects of line number directives and other pragmas.
A client that only cares about what files the lexer processes, like dependency generation, can use this more straightforward
callback instead of `PPCallbacks::FileChanged()`. Clients that want the pragma directive effects as well can keep using `FileChanged()`.
A use case where `PPCallbacks::LexedFileChanged()` is particularly simpler to use than `FileChanged()` is in a situation
where a client wants to keep track of lexed file changes that include changes from/to the predefines buffer, where it becomes
unnecessary complicated trying to use `FileChanged()` while filtering out the pragma directives effects callbacks.
Also take the opportunity to provide information about the prior `FileID` the `Lexer` moved from, even when entering a new file.

This transform is responsible for a long-standing miscompile
as discussed in issue #47012 (was bugzilla #47668).
There was a proposal to correct it in D88432, but that was
abandoned and there hasn't been any recent activity to fix
it AFAICT.
The original patch D45108 started with a constant-shift-only
restriction and only expanded during review, so I don't think
there's much risk of perf regression on the motivating code.
This is a followup to D128847. The `AffineMap::getPermutedPosition` method performs a linear scan of the map, thus the previous implementation had asymptotic complexity of `O(|topSort| * |m|)`. This change reduces that to `O(|topSort| + |m|)`.

getPointerAlignment and ConstantPoolSDNode::getAlign only consider
the alignment of the object. If we already have a non-zero offset
into the offset that may have reduced the alignment.
Since the base pointer will become an LUI with the old offset, we
need to be sure the new offset fits in the alignment of the address
that will be used to create the LUI immediate.
I'm not sure it is possible to have a non-zero offset in the
GlobalAddressSDNode or ConstantPoolSDNode at this point today so this
may only be a theoretical bug.

This review is extracted from D96035.
This patch adds possibility to keep not only DwarfStringPoolEntry, but also
pointer to it. The DwarfStringPoolEntryRef keeps reference to the string map entry.
String map keeps string data and corresponding DwarfStringPoolEntry
info. Not all string map entries may be included into the result,
and then not all string entries should have DwarfStringPoolEntry
info. Currently StringMap keeps DwarfStringPoolEntry for all entries.
It leads to extra memory usage. This patch allows to keep
DwarfStringPoolEntry info only for entries which really need it.

Previous implementation splits value ranges around threads. Because of
very different performance of testing functions over different ranges,
CPU utilization were poor. Current implementation split test range
over small pieces and threads take the pieces when they finish with
previous. Therefore the CPU load is constant during testing.

One motivation to add support for these types are the LD1Q/ST1Q
instructions in SME, for which we have defined a number of load/store
intrinsics which at the moment still take a `<vscale x 16 x i1>` predicate
regardless of their element type.
This patch adds basic support for the nxv1i1 type such that it can be passed/returned
from functions, as well as some basic support to support some existing tests that
result in a nxv1i1 type. It also adds support for splats.
Other operations (e.g. insert/extract subvector, logical ops, etc) will be
supported in follow-up patches.

This function is well-defined for an instruction that doesn't access
memory (and thus trivially doesn't alias anything in the AST), so
drop the assert. We can end up with a readnone call here if we
originally created a MemoryDef for an indirect call, which was
later replaced with a direct readnone call.
