Follow-up for D74433
What the function returns are almost standard BFD names, except that "ELF" is
in uppercase instead of lowercase.
This patch changes "ELF" to "elf" and changes ARM/AArch64 to use their BFD names.
MIPS and PPC64 have endianness differences as well, but this patch does not intend to address them.
Advantages:
* llvm-objdump: the "file format " line matches GNU objdump on ARM/AArch64 objects
* "file format " line can be extracted and fed into llvm-objcopy -O literally.
(https://github.com/ClangBuiltLinux/linux/issues/779 has such a use case)
Affected tools: llvm-readobj, llvm-objdump, llvm-dwarfdump, MCJIT (internal implementation detail, not exposed)

Test files in the same directory share the same %T. %T is easy to
misuse and cause race conditions (when running concurrently) so it has
been deprecated since D48842 (see docs/CommandGuide/lit.rst).
While here, add `rm -rf %t.dir` so that tests cannot depend on old files lying around.

Summary:
This removes the %T/dwo directory before calling ld.lld in ELF/lto/thinlto-debug-fission.ll so that
files aren't left over from previous runs.

Summary:
This adds support to option -plugin-opt=dwo_dir=${DIR}. This option is used to specify the directory to store the .dwo files when LTO and debug fission is used
at the same time.
