This patch improves the handling of MCU data by consolidating multiple
copies of hard-coded MCU data into a single location, and adds a new function
to be used as a single entry point for the extraction of MCU data for the
selected MCU.

This ensures the data is only extracted once per invocation of the
driver/compiler, whilst previously, the data for the MCU is extracted each time
it is needed.

Some notes:
- The GNU assembler doesn't do anything with the -mmcu option beyond setting up
  the CPU ISA, so if the GCC driver passes it the -mcpu option, which it will
  always do if -mmcu is specified, then it is redundant to also pass it -mmcu.
- The indenting in some places (e.g. msp430_select_hwmult_lib) looks wrong in
  the patched file, but to make the diff a lot easier to read I have kept the
  indenting the same as it was before. I can fix this after the patch is
  accepted.

FWIW, another way to address the indentation issue is with the diff -b
option which says to ignore whitespace differences.

Regardless, yes, please clean up any indentation issues.

Presumably we aren't supporting switching the selected mcu via

I guess we only run this once, so the linear search isn't a serious
compile-time issue?

Assuming we don't care about switching the selected mcu within a
compilation unit, OK for the trunk.

No that's not supported at the moment.

Given that 430X devices support 430 and 430X ISA instructions, I suppose this is
something that could be added in the future. Similar to (but not as
complicated as), ARM arm/thumb interworking.

True, this is an old FIXME from the original port, but since we are now only
searching this array a maximum of one time now, it's not important.

Great, thanks for the review,

+Some tests in this directory are run in a msp430-specific "torture" style,
+where all target specific options (that change code generation) are each used
+on each test source file in turn.
+
+The criteria for this torture style of testing is:
+  - The source file has a .c suffix
+  - The source file is in this "devices" subdirectory of the msp430 tests
+  - Somewhere in the test file name matches the regex:
+    [a-z0-9]+430[a-z0-9_]+(?=\.c).
+
+Some of the options used to run the tests will produce warnings/errors for the
+mcus, so ensure the test has dg-warning and dg-error directives as appropriate.
