	PR libstdc++/57060

	__gthread_equal.
	(operator<(thread::id, thread::id)): Add comment.
	(this_thread::get_id()): Do not use __gthread_self for single-threaded
	programs using glibc.

"register_operand" was a bit confusing.  Also some other minor cleanups.


	* (cstore<mode>4_unsigned): Use gpc_reg_operand instead of
	register_operand.  Remove empty constraints.  Use std::swap.
	(cstore_si_as_di, cstore<mode>4_signed_imm,
	cstore<mode>4_unsigned_imm, cstore<mode>4 for GPR): Use
	gpc_reg_operand instead of register_operand.
	(cstore<mode>4 for FP): Use gpc_reg_operand instead of
	register_operand.  Remove empty constraints.

        * common/config/msp430/msp430-common.c (msp430_handle_option):
	Pass both -mmcu and -mcpu on to the back end if they are both
	defined.
	* config/msp430/msp430.c (hwmult_name): New function.
        (msp430_option_override): If an unrecognised MCU name is
	detected only warn if the user has not provided suitable
        -mhwmult and -mcpu options.  Use msp430_warn_mcu to control
	warning messages.  Generate warnings about conflicts between
	-mmcu and -mcpu and -mhwmult options. 
	If neither -mcpu nor -mmcu have been specified but -mhwmult=
	f5series has the select the 430X isa.
	(msp430_no_hwmult): If -mmcu has not been specified and
	msp430_hwmult_type is AUTO then return true.
	* config/msp430/msp430.h (EXTRA_SPEC_FUNCTIONS): Define.
	(LIB_SPEC): Add hardware multiply library selection.
	* config/msp430/t-msp430: Delete hardware multiply multilibs.
	Add rule to build driver-msp430.o
	* config/msp430/driver-msp430.c: New file.
	* config/msp430/msp430.opt (warn-mcu): New option.
	* doc/invoke.texi: Update description of -mhwmult=auto.
        Document -mwarn-mcu option.

tests	* gcc.target/msp430/msp_abi_div_funcs.c: New test.
	* gcc.target/msp430/mul_main.h: New test support file.
	* gcc.target/msp430/mul_none.c: New test.

	* gcc.target/msp430/mul_f5.c: New test.

libgcc	* config/msp430/mpy.c (__mulhi3): Use a faster algorithm.
	Allow for the second argument being negative.
	* config.host (extra_parts): Define for MSP430.  Create separate
	libraries for each of the hardware multiply formats.
	* config/msp430/lib2hw_mul.S: Build only the multiply routines
	that are needed.
	* config/msp430/lib2mul.c: Likewise.
	* config/msp430/t-msp430 (LIB2ADD): Remove lib2hw_mul.S.
	Add rules to build hardware multiply libraries.

This implements cstore for the last case we do not yet handle, using
the superopt algo from the venerable CWG.  The only integer cases we
do still not handle after this are for -m32 -mpowerpc64.


	* (cstore<mode>4_signed): New expander.
	(cstore<mode>4): Call it.
