[ELF] Split up emulation.s per backend emulation.s is testing multiple architectures, which means it needs all the corresponding backends enabled, which might not be true for all developers (for example, I don't have PPC or MIPS enabled). Rather than marking the entire test as unsupported for such developers, split it up per backend to get better testing granularity.

[ELF] Inspect -EL & -EB for OUTPUT_FORMAT(default, big, little) Choose big if -EB is specified, little if -EL is specified, or default if neither is specified. The new behavior matches GNU ld.

Recognize FreeBSD specific BFD names in OUTPUT_FORMAT Summary: After rLLD344952 ("Add OUTPUT_FORMAT linker script directive support"), using BFD names such as `elf64-x86-64-freebsd` the `OUTPUT_FORMAT` linker script command does not work anymore, resulting in errors like: ``` ld: error: /home/dim/src/clang800-import/stand/efi/loader/arch/amd64/ldscript.amd64:2: unknown output format name: elf64-x86-64-freebsd >>> OUTPUT_FORMAT("elf64-x86-64-freebsd", "elf64-x86-64-freebsd", "elf64-x86-64-freebsd") >>> ^ ``` To fix this, recognize a `-freebsd` suffix in BFD names, and also set `Configuration::OSABI` to `ELFOSABI_FREEBSD` for those cases. Add and/or update several test cases to check for the correct results of these new `OUTPUT_FORMAT` arguments.
