ARM64: initial backend import This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. llvm-svn: 205090

[llvm-objdump] Print file format in lowercase to match GNU output. Summary: GNU objdump prints the file format in lowercase, e.g. `elf64-x86-64`. llvm-objdump prints `ELF64-x86-64` right now, even though piping that into llvm-objcopy refuses that as a valid arch to use.

; CHECK-ELF: Disassembly of section .text
[llvm-objdump] -d: print `00000000 <foo>:` instead of `00000000 foo:` The new behavior matches GNU objdump. A pair of angle brackets makes tests slightly easier. `.foo:` is not unique and thus cannot be used in a `CHECK-LABEL:` directive. Without `-LABEL`, the CHECK line can match the `Disassembly of section` line and causes the next `CHECK-NEXT:` to fail. ``` Disassembly of section .foo: 0000000000001634 .foo: ``` Bdragon: <> has metalinguistic connotation. it just "feels right" Reviewed By: rupprecht Differential Revision: https://reviews.llvm.org/D75713
