Convert mov to lea only if needed
We can convert mov to lea only if there are R_386_GOT32/R_X86_64_GOTPCREL
relocations against non IFUNC symbols.

	* elf32-i386.c (need_convert_mov_to_lea): New.
	(elf_i386_check_relocs): Set need_convert_mov_to_lea if needed.
	(elf_i386_convert_mov_to_lea): Return TRUE if
	need_convert_mov_to_lea is unset.
	* elf64-x86-64.c (need_convert_mov_to_lea): New.
	(elf_x86_64_check_relocs): Set need_convert_mov_to_lea if needed.
	(elf_x86_64_convert_mov_to_lea): Return TRUE if
	need_convert_mov_to_lea is unset.
