Chris Bieneman 21c9452305 [DX][ObjYAML] Support for parsing DXIL part
This patch adds support for parsing the DXIL part data into the

data and stores serialized bitcode after the headers.

Chris Bieneman 129c056d62 [ObjectYAML][DX] Support yaml2dxcontainer
This patch adds a the first bits of support for a yaml representation
of dxcontainer files.

Since the YAML representation's primary purpose is testing
infrastructure, the yaml representation supports both verbose and a
more friendly format by making computable sizes and offsets optional.
If provided they are validated to be correct, otherwise they are
computed on the fly during emission.

As I expand the format I'll be able to make more size fields optional,
and I will continue to make the format easier to work with.

Depends on D124804

Sam Clegg 875ee937ae [lld][WebAssembly] Handle TLS symbols in older object file
In older versions of llvm (e.g. llvm 13), symbols were not individually
flagged as TLS.  In this case, the indent was to implicitly mark any
symbols defined in TLS segments as TLS.  However, we were not performing
this implicit conversion if the segment was explicitly marked as TLS

As it happens, llvm 13 was branched between the addition of the segment
flag and the addition of the symbol flag. See:

- segment flag added: https://reviews.llvm.org/D102202
- symbol flag added: https://reviews.llvm.org/D109426

Testing this is tricky because the assembler will imply the TLS status
of the symbol based on the segment its declared in, so we are forced to
use a yaml file here.

Adrian Prantl 8bd8dd16e2 Extend obj2yaml to optionally preserve raw __LINKEDIT/__DATA segments.
I am planning to upstream MachOObjectFile code to support Darwin
chained fixups. In order to test the new parser features we need a way
to produce correct (and incorrect) chained fixups. Right now the only
tool that can produce them is the Darwin linker. To avoid having to
check in binary files, this patch allows obj2yaml to print a hexdump
of the raw LINKEDIT and DATA segment, which both allows to
bootstrap the parser and enables us to easily create malformed inputs
to test error handling in the parser.

This patch adds two new options to obj2yaml:

  -raw-data-segment
  -raw-linkedit-segment

Heejin Ahn 3ec1760d91 [WebAssembly] Remove WasmTagType
This removes `WasmTagType`. `WasmTagType` contained an attribute and a
signature index:
```
struct WasmTagType {
  uint8_t Attribute;
  uint32_t SigIndex;
};
```

Currently the attribute field is not used and reserved for future use,
and always 0. And that this class contains `SigIndex` as its property is
a little weird in the place, because the tag type's signature index is
not an inherent property of a tag but rather a reference to another
section that changes after linking. This makes tag handling in the
linker also weird that tag-related methods are taking both `WasmTagType`
and `WasmSignature` even though `WasmTagType` contains a signature
index. This is because the signature index changes in linking so it
doesn't have any info at this point. This instead moves `SigIndex` to
`struct WasmTag` itself, as we did for `struct WasmFunction` in D111104.

In this CL, in lib/MC and lib/Object, this now treats tag types in the
same way as function types. Also in YAML, this removes `struct Tag`,
because now it only contains the tag index. Also tags set `SigIndex` in
`WasmImport` union, as functions do.

I think this makes things simpler and makes tag handling more in line
with function handling. These two shares similar properties in that both
of them have signatures, but they are kind of nominal so having the same
signature doesn't mean they are the same element.

Also a drive-by fix: the reserved 'attirubute' part's encoding changed
from uleb32 to uint8 a while ago. This was fixed in lib/MC and
lib/Object but not in YAML. This doesn't change object files because the
field's value is always 0 and its encoding is the same for the both
encoding.

This is effectively NFC; I didn't mark it as such just because it
changed YAML test results.
