[PATCH] D16201: [ELF/AArch64] - Implemented set of R_AARCH64_TLSDESC_* relocations.

This patch is required because clang only implements the tlsdesc dialect for aarch64. GCC implements both dialects, so you can:

$ gcc test.c -fPIC -o test.o -c -mtls-dialect=trad
$ readelf -r test.o

Relocation section '.rela.text' at offset 0x248 contains 3 entries:

  Offset          Info           Type           Sym. Value    Sym. Name + Addend

000000000008  000a00000201 R_AARCH64_TLSGD_A 0000000000000000 foo + 0
00000000000c  000a00000202 R_AARCH64_TLSGD_A 0000000000000000 foo + 0
000000000010  000c0000011b R_AARCH64_CALL26  0000000000000000 __tls_get_addr + 0

Also, even is clang implements the traditional TLS dialect for aarch64, we do need to support tlsdesc one (and it is the default for aarch64).
