Create COFF/, ELF/, and Minidump and move tests there.
Also
* Rename `*.test` to `*.yaml`
* For yaml2obj RUN lines, use `-o %t` instead of `> %t` for consistency.
We still have tests that check stdout is the default output, e.g.
multi-doc.test
* Update tests to consistently use `##` for comments.
`#` is for RUN and CHECK lines.
* Merge symboless-relocation.yaml and invalid-symboless-relocation.yaml to ELF/relocation-implicit-symbol-index.test

The address difference between two sections in a PT_LOAD is a constant.
Consider a hypothetical case (pagesize can be very small, say, 4).
```
.text sh_addralign=4
.text.hot sh_addralign=16
```
If we set p_align to 4, the PT_LOAD will be loaded at an address which
is a multiple of 4. The address of .text.hot is guaranteed to be a
multiple of 4, but not necessarily a multiple of 16.
This patch deletes the constraint
if (SHeader->sh_offset == PHeader.p_offset)

Linkers (ld.bfd/gold/lld) place the section header table at the very
end. This allows tools to strip it, which is optional in executable/shared objects.
In addition, if we add or section, the size of the section header table
will change. Placing the section header table in the end keeps section
offsets unchanged.
yaml2obj currently places the section header table immediately after the
program header. Follow what linkers do to make offset updating easier.

We use both -long-option and --long-option in tests. Switch to --long-option for consistency.
In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf.
While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf).

Sometimes program headers have larger alignments than any of the
sections they contain. Currently yaml2obj can't produce such files. A
bug recently appeared in llvm-objcopy that failed in such a case. I'd
like to be able to add tests to llvm-objcopy for such cases.
This change adds an optional alignment parameter to program headers that
will be used instead of calculating the alignment.
