[MSP430] Get the DWARF pointer size from MCAsmInfo instead of DataLayout.

[MSP430] Get the DWARF pointer size from MCAsmInfo instead of DataLayout.
This change will allow to put code pointers in DWARF info fields that are larger than actual pointer size, e.g. 16-bit pointers into 32-bit fields.
The need for this came up while creating support for MSP430 in LLDB. MSP430-GCC already generates DWARF info with 32-bit fields, so this change is necessary for LLDB to maintain compatibility with both GCC and LLVM binaries. Moreover, right now in LLDB there is no support for having DWARF pointer size different from ELF header type, e.g. 16-bit DWARF info within ELF32, and it seems there is no such thing as ELF16.
Since other mainline targets are made to have the same pointer size in both MCAsmInfo and DataLayout, there is no need to change anything there.

DebugInfo: Correct/improve type formatting (pointers to function types especially)
This does add some extra superfluous whitespace (eg: "int *") intended
to make the Simplified Template Names work easier - this makes the
DIE-based names match more exactly the clang-generated names, so it's
easier to identify cases that don't generate matching names.
(arguably we could change clang to skip that whitespace or add some
fuzzy matching to accommodate differences in certain whitespace - but
this seemed easier and fairly low-impact)

not expected, so we use DW_FORM_udata to encode the

[MSP430] Enable some basic support for debug information
This commit technically permits LLVM to emit the debug information for ELF files for MSP430 architecture. Aside from this, it only defines the register numbers as defined by part 10.1 of MSP430 EABI specification (assuming the 1-byte subregisters share the register numbers with corresponding full-size registers).
This commit was basically tested by me with TI-provided GCC 8.3.1 toolchain by compiling an example program with `clang` (please note manual linking may be required due to upstream `clang` not yet handling the `-msim` option necessary to run binaries on the GDB-provided simulator) and then running it and single-stepping with `msp430-elf-gdb` like this:
```
$sysroot/bin/msp430-elf-gdb ./test -ex "target sim" -ex "load ./test"
(gdb) ... traditional GDB commands follow ...
```
While this implementation is most probably far from completeness and is considered experimental, it can already help with debugging MSP430 programs as well as finding issues in LLVM debug info support for MSP430 itself.
One of the use cases includes trying to find a point where UBSan check in a trap-on-error mode was triggered.
The expected debug information format is described in the [MSP430 Embedded Application Binary Interface](http://www.ti.com/lit/an/slaa534/slaa534.pdf) specification, part 10.
