The current support for V1 ABI in LLD is incomplete.
This patch removes V1 ABI support and changes the default behavior to V2 ABI,
issuing an error when using the V1 ABI. It also updates the testcases to V2
and removes any V1 specific tests.

Android AOSP has started specifying -m aarch64_elf64_le_vec as supported
by gold and BFD. This is a simple change to add the emulation so that LLD
doesn't immediately error when used as a linker in an AOSP build.

This patch adds changes to start supporting the Power 64-Bit ELF V2 ABI.
This includes:
- Changing the ElfSym::GlobalOffsetTable to be named .TOC.
- Creating a GotHeader so the first entry in the .got is .TOC.
- Setting the e_flags to be 1 for ELF V1 and 2 for ELF V2

MIPS ABIs require that if an executable file uses non-PIC model, the
EI_ABIVERSION entry in the ELF header should be incremented from 0 to 1.
That allows obsoleted / limited dynamic linkers refuse to link them.

Currently LLVM can only generate PIC code for MIPS64 with the N64 as
it uses the idiom "isPositionIndependent() || IsABI_N64()" throughout the
MIPS backend. r293164 changed this, causing test failures for LLD.
This patch changes the tests minimally to preserve existing test coverage
and one case where the test was "right" in the wrong circumstance.

In the FreeBSD world x86_64 still has its original name, amd64. Accept
it as an alias.

LLD still does not produce a correct combination of MIPS ELF flags if
input files have different sets of ELF flags (i.e. EF_MIPS_ARCH_32 and
EF_MIPS_ARCH_32R2). But now we do not stick to "R2" ABI version and can
emit EF_MIPS_ARCH_32R6 for example.

This patch adds -m elf32_x86_64 to lld. But it doesn't generate working
x32 binaries.

The patch configure ELF header flags for MIPS target. For now the flags
are hard coded. In fact they depends on ELF flags of input object files
and selected emulation.

This option is passed by clang driver if the target triple
is "aarch64-unknown-linux".
