Georgii Rymar 6e779e953e [ObjectYAML] - Redefine LLVM_YAML_IS_SEQUENCE_VECTOR(llvm::yaml::Hex*) as LLVM_YAML_IS_FLOW_SEQUENCE_VECTOR.
I am using it in https://reviews.llvm.org/D69399.

This change changes how obj2yaml dumps arrays of `llvm::yaml::Hex8/llvm::yaml::Hex16/llvm::yaml::Hex32`
from:

```
PayloadBytes:
- 0x01
- 0x02
...
```

To

```
PayloadBytes:    [ 0x01, 0x02, ... ]
```

The latter way is shorter and looks better for arrays.

Chris Bieneman 432ba9d89a [macho2yaml] Don't write empty linkedit data
Since I stopped writing empty export tries it causes LinkEdit to potentially be completely empty which results in invalid yaml being generated.

To prevent this we skip linkedit data if it is empty.

Chris Bieneman 8ff0c11357 [yaml2obj] Remove --format option in favor of YAML tags
Summary:
Our YAML library's handling of tags isn't perfect, but it is good enough to get rid of the need for the --format argument to yaml2obj. This patch does exactly that.

Instead of requiring --format, it infers the format based on the tags found in the object file. The supported tags are:

!ELF
!COFF
!mach-o
!fat-mach-o

I have a corresponding patch that is quite large that fixes up all the in-tree test cases.

Chris Bieneman be70933d3c [obj2yaml][yaml2obj] Adding enumFallback for MachO load commands
This adds support for handling unknown load commands, and a bogus_load_command tests.

Unknown or unsupported load commands can be specified in YAML by their hex value.
