Use common_val_print_checked in print_variable_and_value
GDB was crashing in "bt full" for a large Ada program. I tracked this
down to a combination of bugs.
The first bug, fixed here, is that print_variable_and_value calls
common_val_print. Normally only the value-printing implementation
should call this; from the top level, common_val_print_checked is
preferred, because it correctly handles values that are wholly
optimized out.
I wasn't able to write a test case for this.

* printcmd.c (print_variable_and_value): Use
common_val_print_checked.
