Fix up ARM constant island pass for Thumb2.

Also fixed up code to fully use the SoImm field for ADR on ARM mode.

Since we have moved unified assembly, switch to ADR instruction instead of a the difficult-to-read .set + add syntax to materialize pc-relative address.
...
Turns out this also fixed a poor code selection on Thumb1. I have no idea why we were using a mov + add to do the same thing as ADR before.

Convert StringMap to using StringRef for its APIs.
...
- Yay for '-'s and simplifications!
- I kept StringMap::GetOrCreateValue for compatibility purposes, this can
eventually go away. Likewise the StringMapEntry Create functions still follow
the old style.

Switch the driver back to always using clang-cc by default (for C++, and
...
regardless of the architecture).
- This is a good default for development & testing; for example without this
any tests using 'clang' in the test suite will fail on PowerPC, since the
driver will avoid using clang.
- We don't want to actually ship something built this way, but that should be
handled via some sort of configuration file.
