current IR-level pass.

The old SjLj EH pass has some problems, especially with the new EH model. Most
significantly, it violates some of the new restrictions the new model has. For
instance, the 'dispatch' table wants to jump to the landing pad, but we cannot
allow that because only an invoke's unwind edge can jump to a landing pad. This
requires us to mangle the code something awful. In addition, we need to keep the
now dead landingpad instructions around instead of CSE'ing them because the
DWARF emitter uses that information (they are dead because no control flow edge
will execute them - the control flow edge from an invoke's unwind is superceded
by the edge coming from the dispatch).

Basically, this pass belongs not at the IR level where SSA is king, but at the
code-gen level, where we have more flexibility.

Check for GCC paths that have the target triple in them.  This is required for a lot of cross-compile toolchains.  Also add some slightly better support for -B.

Stop emitting instructions with the name "tmp" they eat up memory and have to be uniqued, without any benefit.

If someone prefers %tmp42 to %42, run instnamer.

Also add rich comparison methods (__eq__ and __ne__) for SBWatchpointLocation.
Modify TestWatchpointLocationIter.py to exercise the new APIs.

Add fuzz testings for the recently added SBTarget APIs related to watchpoint manipulations.

the rule that defines the implicit copy constructor/implicit copy
asssignment operator as deleted when a move constructor or move

number of people because Boost 1.47.0's shared_ptr fails to declare a
copy constructor.
