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.

We might crash when the dynamic symbols table is empty (or not found)
and --hash-symbols is requested. Both .hash and .gnu.hash logic is affected.
The patch fixes this issue.

Now we are able to have default values for macros in YAML descriptions.
I've applied it for hash table tests and also fixed few copy-paste issues
in their comments.

Start using the `checkGNUHashTable` helper which was recently introduced to report
a proper warning when a GNU hash table goes past the end of the file.

This validates that sections listed for a segment in the YAML
declaration are ordered by their file offsets.
It might help to simplify the file size computation, but also
is useful by itself as helps to avoid issues in test cases and
to maintain their readability.

We have scenarios when the logic of --elf-hash-histogram/--hash-symbols/--hash-table
options might crash when given a broken hash table.
This patch adds pre-checks for tables for these 3 options
and provides test cases.

We are able to reduce `-DBITS=32/64` to reduce this test case.
I've rewrote the comments we had to generalize them and
fix wrong computations they contained.

`PAddr` corresponds to `p_paddr` of a program header, which is the segment's physical
address for systems in which physical addressing is relevant. `p_paddr` is often equal
to `p_vaddr`, which is the virtual address of a segment.
This patch changes the default for `PAddr` from 0 to a value of `VAddr`.

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`
