x86: Restore PC16 relocation overflow check
The x86-64 psABI has
---
A program or object file using R_X86_64_8, R_X86_64_16, R_X86_64_PC16
or R_X86_64_PC8 relocations is not conformant to this ABI, these
relocations are only added for documentation purposes.
---
Since x86 PC16 relocations have been used for 16-bit programs in an ELF32
or ELF64 container, PC16 relocation should wrap-around in 16-bit address
space. Revert
