[BPF] Make sure ALU32 feature is set in MCSubtargetInfo for mcpu=v3

`BPF.td` is used to generate (among other things) `MCSubtargetInfo`
setup function for BPF target.
Specifically, the `BPFGenSubtargetInfo.inc` file:

    enum {
      ALU32 = 0,
      ...
    };
    ...
    extern const llvm::SubtargetSubTypeKV BPFSubTypeKV[] = {
      { "generic", { { { 0x0ULL, ... } } }, ... },
      { "probe",   { { { 0x0ULL, ... } } }, ... },
      { "v1",      { { { 0x0ULL, ... } } }, ... },
      { "v2",      { { { 0x0ULL, ... } } }, ... },
      { "v3",      { { { 0x1ULL, ... } } }, ... },
    };
    ...
    static inline MCSubtargetInfo *createBPFMCSubtargetInfoImpl(...) {
      return new BPFGenMCSubtargetInfo(..., BPFSubTypeKV, ...);
    }

The `SubtargetSubTypeKV` is defined in `MCSubtargetInfo.h` as:

    /// Used to provide key value pairs for feature and CPU bit flags.
    struct SubtargetSubTypeKV {
      const char *Key;                      ///< K-V key string
      FeatureBitArray Implies;              ///< K-V bit mask
      FeatureBitArray TuneImplies;          ///< K-V bit mask
      const MCSchedModel *SchedModel;
      ...
    }

The first bit array specifies features enabled by default for a
specific CPU. This commit makes sure that this information is
communicated to `tablegen` and correct `BPFSubTypeKV` table is
generated. This allows tools like `objdump` to detect available
features when `--mcpu` flag is specified.

[DebugInfo] Fix file path separator when targeting windows.

This fixes two problems:

1. When crossing compiling for windows on linux, source file path in debug info is concatenated with directory by host native separator ('/'). For windows local build, they are concatenated by '\'. This causes non-determinism bug.

  The solution here is to let `LangOptions.UseTargetPathSeparator` to control if we should use host native separator or not.

2. Objectfile path in CodeView also uses host native separator when generated.

 It's fixed by changing the path separator in `/Fo` to '\' if the path is not an absolute path when adding the `-object-file-name=` flag.

[Parse] Remove TimeTraceScope for "ParseTemplate"

Fix https://github.com/llvm/llvm-project/issues/56554

```
#include "1.h"
#include "2.h"
int foo();
```

Suppose that 1.h ends with a template function. When parsing the function,
the `ParseFunctionDefinition` call after the TimeTraceScope object
may consume a `r_brace` token and lex the end of file (1.h), resulting
in an ExitFile event in SemaPPCallbacks::FileChanged. This event will call `llvm::timeTraceProfilerEnd();`,
which incorrectly ends "ParseTemplate" instead of "Source" (1.h).
Once 2.h has been fully parsed, the destructor of 1.h's TimeTraceScope object
will end "Source" (1.h).

This behavior erroneously extends the end of "Source" (1.h), which makes
"Source" (2.h) appear to be nested inside "Source" (1.h). This bug is difficult
to fix correctly in an elegant way, and we have two options: either end
"ParseTemplate" when ending "Source" (1.h), or delay the ExitFile event.

However, both approaches require complex code. For now, we can remove the
"ParseTemplate" TimeTraceScope. This can be re-added if properly repaired.

A hlfir.expr can be defined by:
  - A transformational intrinsic (e.g. hlfir.matmul)
  - hlfir.as_expr
  - hlfir.elemental

hlfir.elemental is easy because there is a compulsory shape operand.
hlfir.as_expr is defined as operating on a variable (defined using a
hlfir.declare). hlfir.declare has an optional shape argument. The
transformational intrinsics do not have an associated shape.

If all extents are known at compile time, the extents for the shape can
be fetched from the hlfir.expr's type. For example, the result of a
hlfir.matmul with arguments who's extents are known at compile time will

the hlfir.shape_of will be canonicalised to a fir.shape operation using
those extents.

If not all extents are known at compile time, shapes have to be read

intrinsics, the shape read from the result box can be queried from the

[Pipelines] Add LoopSink and DivRemPairs to LTO post-link pipeline

As pointed out in D148010, these passes are missing from the LTO
post-link pipeline. They are present in the pre-link pipeline,
but LoopSink is completely useless there (it will always be fully
undone by LICM post-link) and DivRemPairs is mostly useless
(I believe most of what it does will be undone by InstCombine).

I've not added RelLookupTableConverterPass, because it's also
disabled in the LTO pre-link pipeline, with a comment that there
is an unresolved issue with full LTO.

Compile-time impact of the extra passes is minimal. Of course,
LoopSink will have a larger impact in PGO builds.

[GVN] Adjust metadata for coerced load CSE

When reusing a load in a way that requires coercion (i.e. casts or
bit extraction) we currently fail to adjust metadata. Unfortunately,
none of our existing tooling for this is really suitable, because
combineMetadataForCSE() expects both loads to have the same type.
In this case we may work on loads of different types and possibly
offset memory location.

As such, what this patch does is to simply drop all metadata, with
the following exceptions:

* Metadata for which violation is known to always cause UB.
* If the load is !noundef, keep all metadata, as this will turn
  poison-generating metadata into UB as well.

This fixes the miscompile that was exposed by D146629.

decide to create a vector epilogue loop. However, this doesn't
take VScaleForTuning into account because we could be targeting a
