[ELF] Move `// REQUIRES:` line to the top llvm-svn: 335676

// REQUIRES: aarch64
[ELF][AArch64] Add support for AArch64 range thunks. The AArch64 unconditional branch and branch and link instructions have a maximum range of 128 Mib. This is usually enough for most programs but there are cases when it isn't enough. This change adds support for range extension thunks to AArch64. For pc-relative thunks we follow the small code model and use ADRP, ADD, BR. This has a limit of 4 gigabytes. Differential Revision: https://reviews.llvm.org/D39744 llvm-svn: 319307
