This change adds an new option --arm-enable-ehabi-descriptors that
enables emitting unwinding descriptors. This provides a mode with a

inside the innards of the Driver implementation, and only ever
implemented to return 'true' for the Darwin OSes. Instead use a more
direct query on the target triple and a comment to document why the
target matters here.

If anyone is worried about this predicate getting wider use or improper
use, I can make it a local or private predicate in the driver.

llvm-svn: 148797

The Driver has a fixed target, whether we like it or not, the
DefaultTargetTriple is not a default. This at least makes things more
honest. I'll eventually get rid of most (if not all) of
DefaultTargetTriple with this proper triple object. Bit of a WIP.

This is the last piece of N3031 (decltype in weird places) - supporting
the use of decltype in a class ctor's member-initializer-list to
specify the base classes to initialize.
