[LV] Return best VPlan together with VF from computeBestVF (NFC). (#190385)

computeBestVF iterates over all VPlans and picks the VF of the most
profitable VPlan. This VPlan is later needed for execution and
additional checks. Instead of retrieving it multiple times later, just
directly return it from computeBestVF.

This removes some redundant lookups.

[llvm-ir2vec] Added Enum for ir2vec embedding mode (#190466)

Currently, the initEmbedding() takes mode as an input. This input is a
string input. This PR introduces a patch to take the input as an enum
value.

[VPlan] Mark unary ops as not having side-effects (NFC). (#190554)

Mark unary ops (only FNeg current) to neither read nor write memory,
similar to binary and cast ops.

Should currently be NFC end-to-end.

[MLIR][NVVM] Add new narrow FP convert Ops (#184291)

This change adds the following NVVM Ops for new narrow FP conversions
introduced in PTX 9.1:
- `convert.{f32x2/bf16x2}.to.s2f6x2`
- `convert.s2f6x2.to.bf16x2`
- `convert.bf16x2.to.f8x2` (extended for `f8E4M3FN` and `f8E5M2` types)
- `convert.{f16x2/bf16x2}.to.f6x2`
- `convert.{f16x2/bf16x2}.to.f4x2`

Reland "[mlir][reducer] Add eraseRedundantBlocksInRegion and getSuccessorForwardOperands API to BranchOpInterface" (#189253)

After fixing undefined symbol and memory leak issues(You can see
previous issue https://github.com/llvm/llvm-project/pull/189150), the PR
would like to reland
it(https://github.com/llvm/llvm-project/pull/187864).

Early exit llvm-bolt when coming across empty data files (#176859)

perf2bolt generates empty fdata files for small binaries and right now
BOLT does this check while parsing by calling `((!hasBranchData() &&
!hasMemData()))`. Instead, early exit as soon as the buffer finishes
reading the data file and exit with error message.

[Polly] Correct integer comparison bit width (#190493)

For making an integer compareable to bool, don't compare it to bool.

Bug occured during the reduction of #190459

[runtimes] Skip custom linker validation for gpu/offload targets (#189933)

This fixes `Host compiler does not support '-fuse-ld=lld'` error when
cross-build libclc for gpu target. Cmake configure command is:
-DRUNTIMES_amdgcn-amd-amdhsa-llvm_LLVM_ENABLE_RUNTIMES=libclc \
-DLLVM_RUNTIME_TARGETS="amdgcn-amd-amdhsa-llvm"
libclc targets only support offload target cross-build and can't link
host executable. The configuration error is false positive for offload.

This PR adds a baseline test to first check if the target can link
executable. If it fails (typical for gpu/offload), we skip the custom
linker validation.

[LV] Additional epilogue tests for find-iv and with uses of IV.(NFC) (#190548)

Additional test coverage for loops not yet supported, with sinkable
find-iv expressions (github.com/llvm/llvm-project/pull/183911) and uses
of the IV.

[VPlan] Refactor FindLastSelect matching to use m_Specific(PhiR) (NFC). (#190547)

Match the select operands directly against PhiR using m_Specific,
binding only the non-phi IV expression. This replaces the generic
TrueVal/FalseVal matching followed by an assert and conditional
extraction.

[llvm][docs] Fix typo (#190150)

[Orc][LibResolver] Fix GNU/Hurd build (#184470)

GNU/Hurd does not put a PATH_MAX static constraint on path lengths. We can instead check the symlink length.

[lldb] Remove VMRange class (NFC) (#190475)

We have a template class `Range` that provides similar functionality and
is much more widely used.

[lldb] Fix section offset of synthesized entry point symbol (#190348)

In the non-ARM case, the offset was left unset, so the symbol
synthesized for the entry point pointed to the start of the containing
section.
As a drive-by change, simplify offset adjustment in ARM case.

[lldb] Bring more diagnostics in compliance with our coding standards (#190410)

The LLVM Coding Standards [1] specify that:

> [T]o match error message styles commonly produced by other tools,
> start the first sentence with a lowercase letter, and finish the last
> sentence without a period, if it would end in one otherwise.

Historically, that hasn't been something we've enforced in LLDB, but in
the past year or so I've started to pay more attention to this in code
reviews. This PR brings more error messages in compliance, further
increasing consistency.

I also adopted `createStringErrorV` where it improved the code as a
drive-by for lines I was already touching.

[clang-repl] Use canonical types in QualTypeToString (#190528)

Use the canonical type when generating type strings to ensure sugared
(e.g. `AutoType`, `DecltypeType`) are resolved before calling
getFullyQualifiedType.

This will revert a few commits that were added to fix these assertions.

[CIR] Use data size in emitAggregateCopy for overlapping copies

Add skip_tail_padding property to cir.copy to handle potentially-overlapping
subobject copies directly, instead of falling back to cir.libc.memcpy. When
set, the lowering uses the record's data size (excluding tail padding) for
the memcpy length. This keeps typed semantics and promotability of cir.copy.

Also fix CXXABILowering to preserve op properties when recreating operations,
and expose RecordType::computeStructDataSize() for computing data size of
padded record types.
