Convert mov to lea for loading address of local common symbol

There is no need to check def_regular when converting mov to lea for
loading address of local symbols since def_regular may be false for
common symbols and SYMBOL_REFERENCES_LOCAL is sufficient.

bfd/

	* elf32-i386.c (elf_i386_convert_mov_to_lea): Don't check
	def_regular.
	* elf64-x86-64.c (elf_x86_64_convert_mov_to_lea): Likewise.

	symbol.
