Before this patch, when an unknown symbol type is used in IFS stub, it
will be treated as a NO_TYPE and parsed without error. This patch makes
llvm-ifs throw an error when this scenario happens.
value() has undesired exception checking semantics and calls
__throw_bad_optional_access in libc++. Moreover, the API is unavailable without
_LIBCPP_NO_EXCEPTIONS on older Mach-O platforms (see
_LIBCPP_AVAILABILITY_BAD_OPTIONAL_ACCESS).
This fixes check-llvm.
st_size may not be of importance to the abi if you are not using
copy relocations. This is helpful when you want to check the abi
of a shared object both when instrumented and not because asan
will increase the size of objects to include the redzone.

This diff changes llvm-ifs to use unified IFS file format
and perform other renaming changes in preparation for the
merging between elfabi/ifs.

This change implements unified text stub format and command line
interface proposed in the elfabi/ifs merge plan.

It appears for Swift there was confusing errors when trying to parse APINotes, when libAPINotes and libInterfaceStub are linked, they both export symbol
`__ZN4llvm4yaml7yamlizeINS_12VersionTupleEEENSt3__19enable_ifIXsr16has_ScalarTraitsIT_EE5valueEvE4typeERNS0_2IOERS5_bRNS0_12EmptyContextE`, and discovered
same symbol defined within llvm-ifs.
This consolidates the boilerplate into YAMLTraits and defers the specific validation in reading the whole input.

This change moves elfabi related code to llvm/InterfaceStub library
so it can be shared by multiple llvm tools without causing cyclic
dependencies.
