[ELF/AArch64] Fix overflow checks for R_AARCH64_{ABS,PREL}{16,32} relocations. ABI specifies the allowed range for these relocations as 2^(n-1) <= X < 2^n. The patch fixes checks and introduces precise tests for these relocations. Differential revision: http://reviews.llvm.org/D14957 llvm-svn: 254146

Align AArch64 and i386 image base to superpage Summary: As for x86_64, the default image base for AArch64 and i386 should be aligned to a superpage appropriate for the architecture. On AArch64, this is 2 MiB, on i386 it is 4 MiB.
