[PATCH 1/2] Remove ada_attribute_name

[Tom Tromey <tromey@adacore.com>]

ada_attribute_name uses an array that must be kept in sync with an
enum -- but the comment here refers to an enum that no longer exists.
Looking at the sole caller, I see this can only be called for two
opcodes.  So, remove this entirely and inline it.
