[AArch64] Better errors for out-of-range fixups When a fixup that can be resolved by the assembler is out of range, we should report an error in the source, rather than crashing. Differential Revision: http://reviews.llvm.org/D18402 llvm-svn: 265120

[COFF, ARM64] Fix symbol offsets in ADRP/ADD/LDR/STR relocations In COFF, a symbol offset can't be stored in the relocation (as is done in ELF or MachO), but is stored as the immediate in the instruction itself. The immediate in the ADRP thus is the symbol offset in bytes, not in pages. For the PAGEOFFSET_12A/L relocations, ignore any offset outside of the lowest 12 bits; they won't have any effect on the ADD/LDR/STR instruction itself but only on the associated ADRP. This is similar to how the same issue is handled for MOVW/MOVT instructions in ELF (see e.g. SVN r307713, and r307728 in lld). This fixes "fixup out of range" errors while building larger object files, where temporary symbols end up as a plain section symbol and an offset, and fixes any cases where the symbol offset mean that the actual target ended up on a different page than the symbol itself.
