AArch64: Add basic relocation processing for llvm-dwarfdump.

This allows llvm-dwarfdump to handle the relocations needed, at least
for LLVM-produced code.

+We're mostly checking that relocations are applied correctly
+here. Currently R_AARCH64_ABS32 is used for references to debug data
+and R_AARCH64_ABS64 is used for program addresses.
+
+A couple of ABS32s, both at 0 and elsewhere, interpreted correctly:
+
+CHECK: DW_AT_producer [DW_FORM_strp] ( .debug_str[0x00000000] = "clang version 3.3 ")
+CHECK: DW_AT_name [DW_FORM_strp] ( .debug_str[0x00000013] = "tmp.c")
+
+A couple of ABS64s similarly:
+
+CHECK: DW_AT_low_pc [DW_FORM_addr] (0x0000000000000000)
+CHECK: DW_AT_high_pc [DW_FORM_addr] (0x000000000000005c)
