This reverts commit 640beb38e7.
That commit caused performance degradtion in Quicksilver test QS:sGPU and a functional test failure in (rocPRIM rocprim.device_segmented_radix_sort).
Reverting until we have a better solution to s_cselect_b64 codegen cleanup

The file seems to have been put in the wrong place in its original
commit. This had the effect of marking all llvm-nm tests as unsupported,
unless X86 was enabled, even for tests that weren't X86 specific.

style `getopt_long`.

"Binary utilities: switch command line parsing from llvm::cl to OptTable"
Users should generally observe no difference as long as they only use intended
option forms. Behavior changes:
* `-t=d` is removed. Use `-t d` instead.
* `--demangle=0` cannot be used. Omit the option or use `--no-demangle` instead.
* `--help-list` is removed. This is a `cl::` specific option.
Note:
* `-t` diagnostic gets improved.
* This patch avoids cl::opt collision if we decide to support multiplexing for binary utilities
* One-dash long options are still supported.
* The `-s` collision (`-s segment section` for Mach-O) is unfortunate. `-s` means `--print-armap` in GNU nm.
* This patch removes the last `cl::multi_val` use case from the `llvm/lib/Support/CommandLine.cpp` library
`-M` (`--print-armap`), `-U` (`--defined-only`), and `-W` (`--no-weak`)
are now deprecated. They could conflict with future GNU nm options.
(--print-armap has an existing alias -s, so GNU will unlikely add a new one.
--no-weak (not in GNU nm) is rarely used anyway.)
`--just-symbol-name` is now deprecated in favor of
`--format=just-symbols` and `-j`.

Exclude AArch64 mapping symbols ($x and $d) for symtab symbolization as
it was done for ARM since D95916 tom bring bots back to green state.
This is implemented by setting SF_FormatSpecific such that
llvm-symbolizer will ignore them, and use this flag to re-implement
llvm-nm --special-syms option which make it work for both targets.

Some of these options have a degree of incidental coverage, or are for

Avoid calling getFlags on a non-existent symbol.
The way this is triggered is by calling strip -N on a binary, which sets
the MH_NLIST_OUTOFSYNC_WITH_DYLDINFO header flag. Then, in the
LC_FUNCTION_STARTS command, nm is trying to print the stripped symbols
and needs the proper checks.
This patch extends D58439 (`llvm/test/{yaml2obj,obj2yaml}/**/*.yaml`) and runs all
`llvm/test/**/*.yaml`
Many directories have configured `.yaml` (see the deleted lit.local.cfg
files). Yet still some don't configure .yaml and have caused stale tests:
* 8c5825befb test/llvm-readobj
* bdc3134e23 test/ExecutionEngine
Just hoist .yaml to `llvm/test/lit.cfg.py`. Also delete .cxx which is
not used. The number of tests running on my machine increases from 38304 to 38309.
The list of new tests:
```
ExecutionEngine/RuntimeDyld/X86/ELF_x86-64_none.yaml
Object/archive-error-tmp.txt

Note: This revision is very similar to D62296.
In D75756, we need `getDynamicSymbolIterators()` to skip first NULL symbol in `.dynsym`. And I believe it might be worth pointing this out in a separate patch to gather you experts' opinions.
I have checked that current code base will not be affected by this change.

To improve consistency and avoid unneeded shell feature (output
redirection).
While here, make other changes to improve consistency
--docnum 1 => --docnum=1
-docnum=x => --docnum=x
Previously we were reporting this error if we were list no symbols
which is not the same thing as the file containing no symbols.
Also, always report the filename when printing errors.
This matches the GNU nm behaviour.

Mostly this adds testing for certain aliases in more explicit ways.
There are also a few tidy-ups, and additions of missing testing, where
the feature was either not tested at all, or not tested explicitly and

This error was never checked.
Original commit message:
It adds a test case for a problem fixed by D66976 <https://reviews.llvm.org/D66976>.
It was introduced by me in D66089 <https://reviews.llvm.org/D66089>.
The error reported was never consumed because of a wrong variable name used,
so it could fail when LLVM_ENABLE_ABI_BREAKING_CHECKS is used.

This restores part of r359311 that was reverted by r359830.
Rewrite the symbol types to fix several issues.
Notable difference is that the type of __init_array_start changes from
't' to 'd'.
GNU nm used to mark ELF symbols relative to .init_array as 't'
https://sourceware.org/bugzilla/show_bug.cgi?id=24505 (before 2.33)
because ".init" is the prefix. The bug was copied by r287803.
