Solution that demontrates the problem.

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US;
rv:1.9.1.4) Gecko/20091016 Firefox/3.5.4

When calling a method that takes an epxression as the parameter, get an error
like the following:

Attempting to JIT compile method
'Catnap.Maps.Impl.EntityMap`1<ShowExpressionBugs.Foo>:Property<int>
(System.Linq.Expressions.Expression`1<System.Func`2<ShowExpressionBugs.Foo,
int>>)' while running with --aot-only.

In this case, I do not believe there should be any JIT compiling happening.

The attached demo solution exhibits the problem.

Reproducible: Always

Steps to Reproduce:
1. Run the demo solution on the device
2. Open the file "app.log" to see the exception messages.
Actual Results:  
Exceptions

Expected Results:  
No exceptions

The demo solution uses Catnap and open source ORM which I have developed.  You
can find the source for that here:
http://code.google.com/p/catnap-orm/source/browse/.  In particular, the class
that is used in the demo is here:
