Remove newly introduced whitespace from warnings.

	* messages.c (as_warn_internal): Remove extra whitespace from
	warning messages.
Add MIPS .module directive

gas/

	* config/tc-mips.c (file_mips_opts_checked): New static global.
	(s_module): New static function.
	(file_ase): Remove.
	(mips_pseudo_table): Add .module handler.
	(mips_set_ase): Add opts argument and use instead of mips_opts.
 	(md_assemble): Use file_mips_check_options.
	(md_parse_option): Update to use file_mips_opts instead of mips_opts.
	(mips_set_architecture): Delete function.  Moved to...
	(mips_after_parse_args): Here.  All logic now applies to
	file_mips_opts first and then copies the final state to mips_opts.
	Move error checking and defaults inference to mips_check_options and
	file_mips_check_options.
	(mips_check_options): New static function.  Common option checking for
	command line, .module and .set.  Use .module values in error messages
	instead of refering to command line options.
	(file_mips_check_options): New static function.  A wrapper for
	mips_check_options with file_mips_opts.  Updates BFD arch based on
	final options.
	(s_mipsset): Split into s_mipsset and parse_code_option.  Settings
	supported by both .set and .module are moved to parse_code_option.
	Warnings and errors are kept in s_mipsset because when
	parse_code_option is used with s_module the warnings are deferred
	until code is generated.  Any setting supporting 'default' value is
	kept in s_mipsset as it is not applicable to s_module. Inferred
	settings are also kept in s_mipsset as s_module does not infer any
	settings.  Use mips_check_options.
	(parse_code_option): New static function derived from s_mipsset.
	(s_module): New static function that implements .module.  Allows file
	level settings to be changed until code is generated.
	(s_cpload, s_cpsetup, s_cplocal): Use file_mips_check_options.
	(s_cprestore, s_cpreturn, s_cpadd, mips_address_bytes): Likewise.
	(mips_elf_final_processing): Update file_ase to file_mips_opts.ase.
	(md_mips_end): Use file_mips_check_options.
	* doc/c-mips.texi: Document .module.
