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.

In D83482 we agreed to name e_* fields that are used for overriding
values (like e_phoff) as EPh* (e.g. EPhOff).
Currently we have a set of e_sh* fields that are named inconsistently
with this rule. This patch renames all of them.

This improves the next points for broken hash tables:
1) Use reportUniqueWarning to prevent duplication when
--hash-table and --elf-hash-histogram are used together.
2) Dump nbuckets and nchain fields. It is often possible
to dump them even when the table itself goes past the EOF etc.

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 had no test for --hash-table in tools/llvm-readobj.
The one we had was in test/Object and checked that
it is possible to dump the hash table even when an object
doesn't have a section header table.
In this patch I created a test, moved and merged the existent one.
During moving I converted it to be YAML based to stop using the
precompiled binary.
