Preserve addend for R_386_GOT32 and R_X86_64_GOT32
We should preserve addend for R_386_GOT32 and R_X86_64_GOT32 as in
"movl $foo@GOT + 4, %eax" and "movq $foo@GOT + 4, %rax".
PR gas/19600
* config/tc-i386.c (md_apply_fix): Preserve addend for
BFD_RELOC_386_GOT32 and BFD_RELOC_X86_64_GOT32.
* testsuite/gas/i386/addend.d: New file.
