[Clang] Fix ClassifyImplicitMemberAccess to handle cases where the access in an unevaluated context is not within a CXXRecordDecl or CXXMethodDecl

ClassifyImplicitMemberAccess assumes that if we are not in a static context then
the DeclContext must be a CXXRecordDecl or a CXXMethodDecl. In the case of the
unevaluated context this may not be true.

This will lead to a crash because contextClass will remain a nullptr.

https://reviews.llvm.org/D146014 removed the dependency on errno from
several targets and added it to the `libc_test` macro. However,
strtol_test_helper is not a `libc_test` but a `cc_library` so it's
missing a dependency.

Only rewrite `scf.yield` when the parent op is supported by
scf-to-spirv.

D132262 tried to simplify `IsMetadataOrEHFrameSection` originally introduced in
D127549 but caused a regression as `.quad` directives in

```
.section .note,"a",@note; note:
.quad extern-note    # extern is undefined

.section .rodata,"a",@progbits; rodata:
.quad extern-rodata  # extern is undefined

.section .nonalloc,"",@progbits; nw:
.quad extern-nw
```

are incorrectly rejected: these differences may be link-time constants and
are allowed in GNU assembler and LLVM MC's non-RISC-V ports.

Relax the conditions to allow these cases. For A-B, A may be defined later, but
this requiresFixups call has to eagerly make a decision. For now, emit ADD/SUB
unless A is `.L*`. This euristic handles many temporary label differences for
.debug_* and .apple_types sections. Ideally we should delay the decision of
PC-relative vs ADD/SUB until A is defined.

Follow-up to D143226

Currently we incorrectly emit R_RISCV_ADD32/R_RISCV_SUB32.
Emit R_RISCV_PLT32 instead. The new behavior matches x86-64 and AArch64.

Or else InstCombine can incorrectly report that no change has been made.

This optimization doesn't really fit into InstCombine since it optimizes multiple instructions at once; there's likely a more comprehensive fix.

Previously, we generate function calls to compare values for sorting. It turns
out that the compiler doesn't inline those function calls. We now directly
generate inlined code. Also, modify the code for comparing values to use less
number of branches.

This improves all sort implementation in general. For arabic-2005.mtx CSR, the
improvement is around 25%.

This patch adds support for reduction of max-intrinsic for scalar

OpenMP dialect reduction operation.

Note: This is a temporary flow. The plan is to move to a flow where
the OpenMP reduction operation is inserted during lowering.

Remove the `-lower-global-dtors-via-cxa-atexit` escape hatch introduced
in D121736 [1], which switched the default lowering of global

deprecated `__mod_term_func` sections.

I added this flag as an escape hatch in case the switch causes any

The bundler accepts both of the following for the --target option:
  hip-amdgcn-amd-amdhsa-gfx900    (no env field)
  hip-amdgcn-amd-amdhsa--gfx900   (blank env field)

The environment field is defined as optional for Triples
in Triple.h. However, in this patch we update the bundler to
internally standardize to include the env field. While users
aren't required to specify an env field when listing targets on
the commandline, bundles generated by the offload-bundler will
include the ABI field.

This standardization simplifies things for APIs that deal with
bundles generated by the clang-offload-bundler tool.

This allows developing and distributing inlining heuristics

allows for fine grained control of the inliner.

most expediant and obvious way to fix several bugs.

This patch uses a single function and single lookup

Without this change the problem is that flangOmpReport and
flangPrintFunctionNames libraries are not built under 'all',
but they are imported targets via LLVMExports.cmake so that
any out-of-tree build that configures upon LLVM+Flang package
will get this CMake error:
```
  The imported target "flangPrintFunctionNames" references the file

     ".../lib/flangPrintFunctionNames.so"

  but this file does not exist.
```

flang-aarch64-out-of-tree buildbot (https://lab.llvm.org/buildbot/#/builders/175)
does not catch this issue, because it does not enable Flang on the first stage.

Summary:
We use `-Xclang` to pass the GPU binary to be embedded. In the case of
multi-source objects this will be passed more than once, but CMake
implicitly deduplicates arguments. Use the special generator to prevent
this from happening.

Summary:
Multi-source object libraries require some additional handling, this
logic wasn't correctly settending the dependency on each filename
individually and was instead using the last one. This meant that only
the last file was built for multi-object libraries.

Use the predicate condition instead of checkFeatures in *GenDAGISel.inc.

This makes the code similar to isel pattern predicates.

checkFeatures is still used by code created by SubtargetEmitter so
we can't remove the string. Backends need to be careful to keep
the string and predicates in sync, but I don't think that's a big issue.

I haven't measured it, but this should be a compile time improvement
for isel since we don't have to do any of the string processing that's
inside checkFeatures.

Auto-upgrade can be expensive, especially UpgradeDebugInfo() since it runs the verifier.

With this patch, we can specify that the imported bitcode is built with the same revision of LLVM, meaning there's no need to run any auto-upgrading. For now, limit this to just debug info since projects like Rust want to support multiple versions of LLVM at the same time (at compiler build time, not at Rust source code build time) and run a subset of the autoupgrade functionality for simplicity.
