This reverts commit rGcd5b308b828e, rGcd5b308b828e, rG8cedf0e2994c.
There are issues to be investigated for polly bots and bots turning on
EXPENSIVE_CHECKS.
To improve consistency and avoid unneeded shell feature (output
redirection).
While here, make other changes to improve consistency

Summary:
This patch could be treated as a rebase of D33960. It also fixes PR35547.
A fix for `llvm/test/Other/close-stderr.ll` is proposed in D68164. Seems
the consensus is that the test is passing by chance and I'm not
sure how important it is for us. So it is removed like in D33960 for now.
The rest of the test fixes are just adding `--crash` flag to `not` tool.
** The reason it fixes PR35547 is
`exit` does cleanup including calling class destructor whereas `abort`
does not do any cleanup. In multithreading environment such as ThinLTO or JIT,
threads may share states which mostly are ManagedStatic<>. If faulting thread
tearing down a class when another thread is using it, there are chances of
memory corruption. This is bad 1. It will stop error reporting like pretty
stack printer; 2. The memory corruption is distracting and nondeterministic in
terms of error message, and corruption type (depending one the timing, it
could be double free, heap free after use, etc.).

tools/llvm-readobj currently contains tests that are either general for
all file types or that mix file types inside. This patch refactors
these test and leaves only general tests in that folder. All other
tests were moved to ELF/COFF/MachO and wasm accordingly.
I tried to minimize amount of changes, so most of the test parts
remained unchanged. Any further refactorings and improvements for
particular tests should be done independently from this patch.

ARMWinEHPrinter was already designed to handle linked PE images
(since d2941b43f4), but resolving symbols didn't consistently
take the image base into account (as linked images seldom have a
symbol table, except for in MinGW setups).
Win64EHDumper wasn't really designed to handle linked images (it would
crash if executed on such a file), but a few concepts (getSymbol,
taking a virtual address instead of a relocation, and
getSectionContaining for finding the section containing a certain
virtual address) can be borrowed from ARMWinEHPrinter.
Adjust ARMWinEHPrinter to print the address of the exception handler
routine as a VA instead of an RVA, consistently with other addresses
in the same printout, and make Win64EHDumper print addresses similarly
for image cases.

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`
