Prior to this change the clang interface stubs format resembled
something ending with a symbol list like this:
Symbols:
a: { Type: Func }
This was problematic because we didn't actually want a map format and
also because we didn't like that an empty symbol list required
"Symbols: {}". That is to say without the empty {} llvm-ifs would crash
on an empty list.
With this new format it is much more clear which field is the symbol
name, and instead the [] that is used to express an empty symbol vector
is optional, ie:
Symbols:
- { Name: a, Type: Func }
or
Symbols: []
or
Symbols:
This further diverges the format from existing llvm-elftapi. This is a
good thing because although the format originally came from the same
place, they are not the same in any way.
