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.

ELF stubs generated from llvm-ifs lacks program headers, which prevents
llvm-ifs from parsing them properly as program headers are required by
llvm's own ELF libraries. This patch adds a few workaround bypass this
limitation.

This patch adds DT_STRSZ into the dynamic section, which was absent
previously. This was a bug and caused failures in other tools.

This reverts commit fd4808887ee47f3ec8a030e9211169ef4fb094c3.
This patch causes gcc to issue a lot of warnings like:
warning: base class ‘class llvm::MCParsedAsmOperand’ should be
explicitly initialized in the copy constructor [-Wextra]
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.

This patch fixed a bug when elbabi was supplied with a tbe file
contains no non-local symbol. Before this patch, it wrote 0 to
sh_info of the .dynsym section, making the ELF stub file invalid.
This patch fixed this issue.
Differential Revision: https://reviews.llvm.org/D96930
Before this change, when reading ELF file, elfabi determines number of
entries in .dynsym by reading the .gnu.hash section. This change makes
elfabi read section headers directly first. This change allows elfabi
works on ELF files which do not have .gnu.hash sections.

This change adds '--write-if-changed' flag to llvm-elfabi tool. When
enabled, llvm-elfabi will not overwrite the existing file if the
content of the file will not be changed, which preserves the
timestamp.

No longer rely on an external tool to build the llvm component layout.
Instead, leverage the existing `add_llvm_componentlibrary` cmake function and
introduce `add_llvm_component_group` to accurately describe component behavior.
These function store extra properties in the created targets. These properties
are processed once all components are defined to resolve library dependencies
and produce the header expected by llvm-config.

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.

`ELFFile<ELFT>` has many methods that take pointers,
though they assume that arguments are never null and
hence could take references instead.
This patch performs such clean-up.

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