[Bug breakpoints/10754] New: breakpoints referring to JITted code should be disabled between runs

[vargaz at gmail dot com]

When a breakpoint is placed on a location which is described by a symbol file
registered using the new JIT interface in gdb 7.0, and the program is restarted,
it will fail with a message like:
Warning:                                                                       
                         
Cannot insert breakpoint 1.                                                    
                         
Error accessing memory address 0x40010200: Input/output error.       

This is because the breakpoint is resolved to the address of a JITted function
which doesn't exist at the start of the next run.

The attached patch fixes this by disabling breakpoint locations referring to
JITted code between runs. Its against the gdb 7.0 sources. I hope its of 
acceptable quality.
