load commands. Added a missing check and made the check for more than
one like other other “more than one” checks. And of course added test cases.

that use the Mach::dylib_command type for the load commands that are
currently used in the MachOObjectFile constructor.
This contains the missing checks for LC_ID_DYLIB, LC_ID_DYLIB, etc.
load commands and the fields for the Mach::dylib_command type.
Also checks that only an MH_DYLIB or MH_STUB_DYLIB has an
LC_ID_DYLIB load command (and others filetype don’t) and there
is not more than one of these load commands.

that use the Mach::dyld_info_command type for the load commands that are

LC_DYLD_INFO_ONLY load commands and the fields for the
Mach::dyld_info_command type.

that use the Mach::linkedit_data_command type for the load commands that are
currently used in the MachOObjectFile constructor.
This contains the missing checks for LC_DATA_IN_CODE and
LC_LINKER_OPTIMIZATION_HINT load commands and the fields for the
Mach::linkedit_data_command type. Checking for other load commands that
use this type will be added later.
Also fixed a couple of places that was using sizeof(MachOObjectFile::LoadCommandInfo)
that should have been using sizeof(MachO::load_command).

This contains the two missing checks for LC_SEGMENT load command fields.
And checks for the Mach-O sections fields that would make them invalid.
With the new checks, some of the existing malformed file checks now trips one
of these instead of the issue it was having before so those tests were adjusted.

This is where an LC_SEGMENT load command has a fileoff field that
extends past the end of the file.
Also fix llvm-nm and llvm-size to remove the errorToErrorCode() call so error messages are printed.
And needed to update a few test cases now that they do print the error messages just a
bit differently.

This allows ErrorAsOutParameter to work better with "optional" errors. For
example, consider a function where for certain input values it is known that
the function can't fail. This can now be written as:
Result foo(Arg X, Error *Err) {
ErrorAsOutParameter EAO(Err);
if (<Error Condition>) {
if (Err)
*Err = <report error>;
else
llvm_unreachable("Unexpected failure!");
}
}
Rather than having to construct an ErrorAsOutParameter under every conditional
where Err is known to be non-null.

a good error message to be produced.
This is nearly the last libObject interface that used ErrorOr and the last one
that appears in llvm/include/llvm/Object/MachO.h . For Mach-O objects this is
just a clean up because it’s version of getSymbolAddress() can’t return an
error.
I will leave it to the experts on COFF and ELF to actually add meaning full
error messages in their tests if they wish. And also leave it to these experts
to change the last two ErrorOr interfaces in llvm/include/llvm/Object/ObjectFile.h
for createCOFFObjectFile() and createELFObjectFile() if they wish.
Since there are no test cases for COFF and ELF error cases with respect to
getSymbolAddress() in the test suite this is no functional change (NFC).

Fix was:
1) Had to regenerate dwarfdump-test-zlib.elf-x86-64, dwarfdump-test-zlib-gnu.elf-x86-64
(because llvm-symbolizer-zlib.test uses that inputs for its purposes and failed).
2) Updated llvm-symbolizer-zlib.test (updated used call function address to match new files +
added one more check for newly created dwarfdump-test-zlib-gnu.elf-x86-64 binary input).
3) Updated comment in dwarfdump-test-zlib.cc.
Original commit message:
[llvm-dwarfdump] - Teach dwarfdump to decompress debug sections in zlib style.
Before this llvm-dwarfdump only recognized zlib-gnu compression style of headers,
this patch adds support for zlib style.
It looks reasonable to support both styles for dumping,
even if we are not going to suport generating of deprecated gnu one.

part of the error message.
As the caller is the one that needs to add the name of where the "object file"
comes from to the error message as the object file could be in an archive, or
coming from a slice of a Mach-O universal file or a buffer created by a JIT.
In the cases of a Mach-O universal file the architecture name may or may not
also need to be printed which is up to the tool code. For example if the tool
code is only selecting the host architecture slice then that architecture name
is never printed.
This patch is the change to the libObject code and there will be follow on
commits for changes to the code for each tool.
