msp430.c (msp430_mcu_names): Rename to msp430_mcu_data, add fields for ISA and hardware multiply support.
* config/msp430/msp430.c (msp430_mcu_names): Rename to
msp430_mcu_data, add fields for ISA and hardware multiply
support. Import latest data from the devices.csv file.
(msp430_override_option): Use the data from the new array.
(msp430_use_f5_series_hwmult): Likewise.
(use_32bit_hwmult): Likewise.
(msp430_no_hwmult): Likewise.
* config/msp430/t-msp430 (MULTILIB_MATCHES): Add matches for new
MCU names.
* doc/invoke.texi (MSP430 Options): Note that if the MCU name is
not recognised then no hardware multiply support is assumed and
that only the MSP430 ISA is allowed.

A value of @samp{auto} can also be given. This tells GCC to deduce the hardware multiply support based upon the MCU name provided by the @option{-mmcu} option. If no @option{-mmcu} option is specified then -@samp{32bit} hardware multiply support is assumed. @samp{auto} is the -default setting. +@samp{32bit} hardware multiply support is assumed.
