so when IfConverter::CopyAndPredicateBlock checks to see if it should ignore
an instruction because it is a branch, it should not check if the branch is
predicated.

This case (when IgnoreBr is true) is only relevant from IfConvertTriangle,
where new branches are inserted after the block has been copied and predicated.
If the original branch is not removed, we end up with multiple conditional
branches (possibly conflicting) at the end of the block.  Aside from any
immediate errors resulting from that, this confuses the AnalyzeBranch functions
so that the branches are not analyzable.  That in turn causes the IfConverter to
think that the "Simple" pattern can be applied, and things go downhill fast
because the "Simple" pattern does _not_ apply if the block can fall through.

This is pretty fragile.  If there are other degenerate cases where AnalyzeBranch
fails, but where the block may still fall through, the IfConverter should not
perform its "Simple" if-conversion.  But, I don't know how to do that with the
current AnalyzeBranch interface, so for now, the best thing seems to be to
avoid creating branches that AnalyzeBranch cannot handle.

Evan, please review!

may try to spill them, and we can't do that.

- Precision toStrings shouldn't print a dot when they have no value.
- Length of char length modifier is now returned correctly.
- Added several fixit tests.

Note: fixit tests are currently broken due to a bug in HighlightRange. Marking as XFAIL for now.

Change the Breakpoint & BreakpointLocation GetDescription methods so they call the BreakpointOptions::GetDescription rather
than picking bits out of the breakpoint options.  Added BreakpointOptions::GetDescription to do this job.  Some more mucking
around to keep the breakpoint listing from getting too verbose.

Change "breakpoint configure" to "breakpoint modify" so it doesn't collide with "breakpoint command"
Change "breakpoint enable/disable" so changing a breakpoint's state doesn't also overwrite the location states.
