Igor Kudrin cfe47f5b32 [ELF/AArch64] Allow only valid dynamic relocations in the output. 
All relocations, which cannot be handled by the dynamic linker,
cause a linking error "rebuild with -fPIC".

Igor Kudrin fea8ed50ef [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.
