"Binary utilities: switch command line parsing from llvm::cl to OptTable"
* `--totals=false` and `--totals=0` cannot be used. Omit the option.
* `--help-list` is removed. This is a `cl::` specific option.
OptTable avoids global option collision if we decide to support multiplexing for binary utilities.
Note: because the tool is simple, and its long options are uncommon, I just drop
the one-dash forms except `-arch <value>` (Darwin style).

gnu size has a number of special cases regarding REL, RELA and STRTAB
sections being considered in size output. To avoid unnecessary
complexity this commit makes llvm size outputs these sections in cases
they have the SHF_ALLOC flag.

SHT_NOTE is the section that consists of
namesz, descsz, type, name + padding, desc + padding data.
This patch teaches yaml2obj, obj2yaml to dump and parse them.
This patch implements the section how it is described here:
https://docs.oracle.com/cd/E23824_01/html/819-0690/chapter6-18048.html
Which says: "For 64–bit objects and 32–bit objects, each entry is an array of 4-byte words in
the format of the target processor"
The official specification is different
http://www.sco.com/developers/gabi/latest/ch5.pheader.html#note_section
And says: "n 64-bit objects (files with e_ident[EI_CLASS] equal to ELFCLASS64), each entry is an array
of 8-byte words in the format of the target processor. In 32-bit objects (files with e_ident[EI_CLASS]
equal to ELFCLASS32), each entry is an array of 4-byte words in the format of the target processor"
Since LLVM uses the first, 32-bit way, this patch follows it.

Clean up some formatting inconsistencies in the error messages and correctly exit with non-zero in all error cases.
Originally submitted as r374771 and then reverted as r374780, this patch fixes the libObject test case in Object/macho-invalid.test.

This patch significantly improves the llvm-size testing. The changes
made are:
1) Change all tests to use yaml2obj instead of assembly or pre-canned
inputs.
2) Move the tests out of the X86 directory, since they don't need to be
there after 1).
3) Increased test coverage.
4) Added comments to explain purpose of tests.
I haven't attempted to add test coverage for all Mach-O related code, as
I am not familiar enough with that file format to be able to.

Many LLVM-based tools already support response files (i.e. files
containing a list of options, specified with '@'). This change simply
updates the documentation and help text for some of these tools to
include it. I haven't attempted to fix all tools, just a selection that
I am interested in.
I've taken the opportunity to add some tests for --help behaviour, where
they were missing. We could expand these tests, but I don't think that's
within scope of this patch.
This fixes https://bugs.llvm.org/show_bug.cgi?id=42233 and
https://bugs.llvm.org/show_bug.cgi?id=42236.

Summary:
llvm-size uses "isText()" etc. which seem to indicate whether the section contains code-like things, not whether or not it will actually go in the text segment when in a fully linked executable.
The unit test added (elf-sizes.test) shows some types of sections that cause discrepencies versus the GNU size tool. llvm-size is not correctly reporting sizes of things mapping to text/data segments, at least for ELF files.
This fixes pr38723.

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.
