Add parsing of known MSP430 MCU types
I am currently testing this patch to see if it introduces any regressions into
the gcc testsuite...

Hi Ilya,
I have now checked my patches in. If you use the latest (development) FSF
sources for GCC and the binutils you should see that correct parsing of the
-mmcu command line option and the correct display of the MSP430 architecture
variant.
Cheers
Nick
