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.

.dynsym and .dynstr are allocatable and therefore normally are placed
before non-allocatable .strtab, .shstrtab, .symtab sections.
But we are placing them after currently what creates a mix of
alloc/non-alloc sections and does not look normal.

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
