This section contains strings specifying libraries to be added to the link by the linker. The strings are encoded as standard null-terminated UTF-8 strings. This patch adds a way to describe and dump SHT_LLVM_DEPENDENT_LIBRARIES sections. I introduced a new YAMLFlowString type here. That used to teach obj2yaml to dump them like: ``` Libraries: [ foo, bar ] ``` instead of the following (if StringRef would be used): ``` Libraries: - foo - bar ``` Differential revision: https://reviews.llvm.org/D70598

## Case 1: test we use "Libraries" when dumping a valid section with a null-terminated string.
|
|
- Name: .deplibs.single
|
|
Type: SHT_LLVM_DEPENDENT_LIBRARIES
|
|
Libraries: [ foo ]

|
## Case 2: the same, but the section has multiple strings.
|
|
- Name: .deplibs.multiple
|
|
Type: SHT_LLVM_DEPENDENT_LIBRARIES
|
|
Libraries: [ foo, bar, foo ]
|
|
## Case 3: test we use "Libraries" when dumping an empty section.
|
|
- Name: .deplibs.empty
|
|
Type: SHT_LLVM_DEPENDENT_LIBRARIES
|
|
Libraries: [ ]

## Case 4: test we use "Content" when dumping a non-null terminated section.
