Massive test suite cleanup to stop everyone from manually having to compute "mydir" inside each test case. 

This has led to many test suite failures because of copy and paste where new test cases were based off of other test cases and the "mydir" variable wasn't updated.

Now you can call your superclasses "compute_mydir()" function with "__file__" as the sole argument and the relative path will be computed for you.

It completes the job of using EvaluateExpressionOptions consistently throughout
the inferior function calling mechanism in lldb begun in Greg's patch r194009. 

It removes a handful of alternate calls into the ClangUserExpression/ClangFunction/ThreadPlanCallFunction which
were there for convenience.  Using the EvaluateExpressionOptions removes the need for them.

Using that it gets the --debug option from Greg's patch to work cleanly.

It also adds another EvaluateExpressionOption to not trap exceptions when running expressions.  You shouldn't
use this option unless you KNOW your expression can't throw beyond itself.  This is:

<rdar://problem/15374885>

At present this is only available through the SB API's or python.

It fixes a bug where function calls would unset the ObjC & C++ exception breakpoints without checking whether
they were set by somebody else already.

This radar extends the notion of one-liner summaries to automagically apply in a few interesting cases

More specifically, this checkin changes the printout of ValueObjects to print on one-line (as if type summary add -c had been applied) iff:
this ValueObject does not have a summary
its children have no synthetic children
its children are not a non-empty base class without a summary
its children do not have a summary that asks for children to show up
the aggregate length of all the names of all the children is <= 50 characters
you did not ask to see the types during a printout
your pointer depth is 0

This is meant to simplify the way LLDB shows data on screen for small structs and similarly compact data types (e.g. std::pair<int,int> anyone?)

Feedback is especially welcome on how the feature feels and corner cases where we should apply this printout and don't (or viceversa, we are applying it when we shouldn't be)

live as long as they needed to.  This led to
equality tests involving persistent variables
often failing or succeeding when they had no
business doing so.

To do this, I introduced the ability for a
memory allocation to "leak" - that is, to
persist in the process beyond the lifetime of
the expression.  Hand-declared persistent
variables do this now.

Separated the "expr --unwind-on-error" behavior into two parts, actual errors (i.e. crashes) which continue to be
controlled by the --unwind-on-error flag, and --ignore-breakpoint which separately controls behavior when a called
function hits a breakpoint.  For breakpoints, we don't unwind, we either stop, or ignore the breakpoint, which makes
more sense.  
Also make both these behaviors globally settable through "settings set".
Also handle the case where a breakpoint command calls code that ends up re-hitting the breakpoint.  We were recursing
and crashing.  Now we just stop without calling the second command.

Adding useful formatting options to the expression (expr) command.
As a side effect of this change, the -d option now supports the same three-values enumeration that frame variables uses (run, don't run, none) instead of a boolean like it did previously

These options do not apply to print, p or po because these are aliased to not take any options.
In order to use them, use expression or expr.

Fix Test11588.py on Linux.  The test was failing because the synthetic type fields were resolving to int instead of long.  A similar change was made in r155144 to eliminate the type specification for an earlier check in this test, so it seemed appropriate here too.

Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite.

This fix does the following:
- make sure all short options are treated as "int"
- make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired
- fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates
- fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value
