x86: Improve TLS transition error check
Provide detailed TLS transition errors when unsupported instructions are
used. Treat R_X86_64_CODE_4_GOTTPOFF and R_X86_64_CODE_6_GOTTPOFF as
R_X86_64_GOTTPOFF when performing TLS transition.

* elf32-i386.c (elf_i386_check_tls_transition): Return different
enums for different errors.
