value_bits_valid: Fix latent bug.
Doing something else, I factored out the bits of the value_bits_valid function that actually handle the check_validity hook, and surprisingly found out that the result was misbehaving. Turns out value_bits_valid has a latent bug. If the value is not lval_computed, or doesn't have a check_validity hook, then we should assume the value is entirely valid, not invalid. This is currently masked by the value->optimized_out check -- I ran the testsuite with a gdb_assert(0) inserted in place of that return being touched by the patch, and it never triggers. Tested on x86_64 Fedora 17. gdb/ 2013-07-04 Pedro Alves <palves@redhat.com> * value.c (value_bits_valid): If the value is not lval_computed, or doesn't have a check_validity hook, assume the value is entirely valid.
