[MSP430][Clang] Update hard-coded MCU data

[jozefl]

Summary

This patch updates MSP430 MCU data to the latest version distributed by
TI, adding support for 451 additional MCUs.

The hardware multiply version supported by each MCU is now stored as an
enum in the MCU data file, rather than a string. The string value passed
to the -mhwmult= option is now also converted to an enum. Using an enum
simplifies the processing of values, as invalid user input can be
canonicalized as a descriptive enum. It also ensures that the hard-coded
MCU data is valid; that there are no values that the parser does not
recognize.

Clang will no longer explicitly disable hwmult features for MCUs that
don't have hardware multiply support, as hwmult feature are already
disabled by default.

The CPU version of each MCU is now stored with the hard-coded MCU data,
so Clang can enable the appropriate LLVM CPU features when a particular
MCU is selected.

The hard-coded MCU data is stored in lexicographic order, which enables
efficient searching of the data with binary search, using
std::lower_bound.

If the patch is acceptable, I would appreciate it if someone would apply
it for me, as I do not have commit access.

Thanks,
Jozef

Fixed clang-tidy warnings.

Now that I am in the process of implementing the processing of the "CPU"
feature, I've realized the decision to store the CPU and HWMult information as
enums instead of strings has some downsides that may outweigh the benefits:

• All string values passed to options need to be first converted to enums before they can be processed
• Enums need to be converted back to strings in for use in diagnostics
• Additional code is required to perform these conversions

If all CPU and HWMult features are stored as strings, no conversions are
necessary, and the overall amount of code that needs to change for this MCU
data update is small.

As mentioned in the original commit message, the benefits of using enums are
that we have a canonical "invalid" value for when the user input is invalid,
and the hard-coded data is guaranteed to be valid (but not necessarily
correct) since all enums used to define features must be defined.

The processing of the CPU feature is much simpler than the hwmult features,
which is why all the conversions to and from enums seem even more unnecessary
now.

What do you think @asl? Should I get rid of the enums?
That is was I'm leaning towards right now.

Thanks,
Jozef

Here's an updated patch that stores the HWMult and CPU data for each MCU as
strings instead of enums. This simplifies the patch as string conversions to
and from enums are no longer required.

Here's an updated patch to fix the win64 failure.

MSVC can't handle the conversion from a ForwardIterator to a const pointer when
the container being searched with std::lower_bound is a std::array. Meanwhile
clang-tidy warns when the type assigned to with the return value of
std::lower_bound is not a pointer, so I can't just change the type declaration
to a lone "auto", and surpressing the clang-tidy warning for this warning
doesn't seem like the best option either.

So I've changed the data type used to store the MCUData to a C-style array, and
also moved its definition into loadMCUData.

Here's an updated patch that fixes some minor nits.

Rebase to fix patch application failure for
clang/test/Misc/target-invalid-cpu-note.c.

[jozefl]

Undo incorrect rebase.

[asl]

Please see comments inline

clang/lib/Driver/ToolChains/MSP430.cpp

43

maybe it would be better to use get instead of load here?

44

Can we simply use MSP430MCUData[] here in order not to fix multiple places when new MCU is added?

46–47

I'd also #undef here for the sake of not polluting everything with extra macros

78

Features is effectively an output argument here. Can it be last argument? Maybe it would be better to name addHWMultFeatures, overall the function just adds them and do not touch existing things in the Features vector?

111–112

StringSwitch?

Thanks, good points, I have addressed them in this updated patch.

It might be worth moving this under hwmult option check, so we do not need to load MCU data again if the option is properly specificed.

Thanks, good point, fixed in the attached patch.
