Simon Marchi aead7601eb Add casts for legitimate integer to enum conversions
This patch is mostly extracted from Pedro's C++ branch.  It adds explicit
casts from integer to enum types, where it is really the intention to do
so.  This could be because we are ...

 * iterating on enum values (we need to iterate on an equivalent integer)
 * converting from a value read from bytes (dwarf attribute, agent
 expression opcode) to the equivalent enum
 * reading the equivalent integer value from another language (Python/Guile)

An exception to that is the casts in regcache.c.  It seems to me like
struct regcache's register_status field could be a pointer to an array of
enum register_status.  Doing so would waste a bit of memory (4 bytes
used by the enum vs 1 byte used by the current signed char, for each
register).  If we switch to C++11 one day, we can define the underlying
type of an enum type, so we could have the best of both worlds.

#ifndef TARGET_DEBUG_H

/* Printers for the debug target. Each prints an object of a given
type to a string that needn't be freed. Most printers are macros,
for brevity, but a few are static functions where more complicated
behavior is needed.
References to these printers are automatically generated by
make-target-delegates. See the generated file target-delegates.c.
In a couple cases, a special printing function is defined and then
used via the TARGET_DEBUG_PRINTER macro. See target.h.
A few methods still have some explicit targetdebug code in
target.c. In most cases this is because target delegation hasn't
been done for the method; but individual cases vary. For instance,
target_store_registers does some special register printing that is
more simply done there, and target_xfer_partial additionally
bypasses the debug target. */
