Instead of referring to stack sizes sections only by name, we can add
section indexes and types to warnings reported.

This replaces `reportError` calls with `reportUniqueWarning` and improves testing
for the code that is related to stack sizes dumping.

Currently we have to set 'Machine' to something in our
YAML descriptions. Usually we use 'EM_X86_64' for 64-bit targets
and 'EM_386' for 32-bit targets. At the same time, in fact, in most
cases our tests do not need a machine type and we can use
'EM_NONE'.
This is cleaner, because avoids the need of using a particular machine.
In this patch I've made the 'Machine' key optional (the default value,
when it is not specified is `EM_NONE`) and removed it (where possible)
from yaml2obj, obj2yaml and llvm-readobj tests.
There are few tests left where I decided not to remove it, because
I didn't want to touch CHECK lines or doing anything more complex
than a removing a "Machine: *" line and formatting lines around.

For describing section/symbol names we can use unique suffixes,
e.g:
```
- Name: '.foo [1]`
- Name: '.foo [2]`
```
It can be a problem (see https://reviews.llvm.org/D79984#inline-734829),
because `[]` are sometimes used to describe a macros:
```
- Name: "[[a0]]"
```
Seems the better approach is to use something else, like "()".
This patch does it and refactors the code related.

Prior to this change, for non-relocatable objects llvm-readobj would
assume that all symbols that corresponded to a stack size section's
entries were in the section specified by the section's sh_link field.
In the presence of an output section description combining
SHF_LINK_ORDER sections linking different output sections, this cannot
be respected, since linker script section patterns are "by name" by
nature. Consequently, the sh_link value would not be correct for all
section entries.
This patch changes llvm-readobj to ignore the section of symbols in a
non-relocatable object.

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
This creates the next subfolders in the test directory:
"COFF", "ELF", "MachO", "wasm".
I've also removed platform specific prefixes, like "coff-*".
One unused binary was removed as well: `Inputs/relocs.obj.elf-mips`
