This very simple and mostly useless operation has no side effects, and
can be used to verify that arguments are making it into gem5, being
operated on, and then that a result can be returned into the simulation.

I've needed this type of macro often when writing code which uses the
M5OP_FOREACH macro, and so rather than re-write it each time, lets just
put a version here. This is such a common type of macro to need that
you'd think it would be part of a standard header somewhere, but to my
knowledge it isn't.

It may be the case that each item M5OP_FOREACH iterates over should end
in a ',' and not a ';', for instance when putting each item into an
array or initializing a structure. If the caller still wants a ';', they
can add it into the definition of the M5OP macro.

These shouldn't be called in fs mode through the m5 utility and
probably shouldn't be called directly either, but this makes them
consistent with the other functions which are mentioned in
asm/generic/m5ops.h.

Make sure all the operations that have constants (and aren't deprecated
or reserved) and present in M5OP_FOREACH in order of their constants.
Also move M5OP_ANNOTATE up so that all the constants are also in order.

Now that the annotation pseudo ops are removed, the subfunction is
always zero. It is no longer decoded within gem5 either. The format of
the pseudo op func/subfunc mechanism is unchanged for compatibility, but
the subfunc field will always be zero now.

Two m5op, load_symbol and dist_toggle_sync are defined with
different name in C and asm version headers 'm5ops.h'
The m5ops are named to m5_load_symbol() and m5_dist_toggle_sync().

The header file with C declarations for m5ops is sometimes needed by
code outside of the util/m5 directory. Move this file to the shared
include directory and factor out flags to a generic asm header. Note
that applications that need to call m5ops still need to link with
libm5.a or implement their own trampolines.

The header file m5ops.h contains a list of constants that should be
shared between the simulator and utilities. Move this header file to a
new top-level directory for shared files and rename constants to make
them suitable for inclusion in the main simulator.
The structure of the shared include directory is as follows:
include/gem5: Files that can be included from C code.
include/gem5/asm: Files that can be included from assembly code.
asm/generic/: Files that aren't guest ISA specific
asm/${isa}/: Files that are guest ISA specific
