The flags massaging in insns.pl could end up with things like double
commas in some pathological cases, which would make insns_flag_index()
very unhappy due to the appearance of an empty argument. Fix this by
processing the flags as a list already in insns.pl.
Be more explicit and consistent in error messages.

Add comments to iflag.c so a human user can have any hope of
figuring out what a particular bitmask actually means.

Move the definitions to a separate file, in order to separate code
from data better.
We can auto-generate more information about the instruction flags, so
let's do so.

Automatically assign values to the instruction flags; we ended up with
a case where pushing flags into the next dword caused comparison
failures due to other places in the code explicitly comparing
field[3].
This creates necessary defines for this not to happen; it also cleans
up a fair bit of the iflag code.
This resolves BR 3392454.

insns-iflags.ph is included from another Perl script, so rename it .ph
(Perl header). Add missing dependency to the main Makefile.
