Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic models without PLT, which uses indirect call via GOT: call *___tls_get_addr@GOT(%reg) where EBX register isn't required as GOT base, instead of direct call: call ___tls_get_addr[@PLT] which requires EBX register as GOT base. Since direct call is 4-byte long and indirect call, is 5-byte long, the extra one byte must be handled properly. For general dynamic model, 7-byte lea instruction before call instruction is replaced by 6-byte one to make room for indirect call. For local dynamic model, we simply use 5-byte indirect call. TLS linker optimization is updated to recognize new instruction patterns. For local dynamic model to local exec model transition, we generate a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte lea instruction. Since linker may convert call ___tls_get_addr[@PLT] to addr32 call ____tls_get_addr when producing static executable, both patterns are recognized. bfd/ * elf64-i386.c (elf_i386_link_hash_entry): Add tls_get_addr.
