99d45c850e Fix problem with C99 inlines and -Werror=missing-prototypes 
Some older versions of gcc (gcc 4.2.1 at least) produce a warning,
promoted to error, on C99 inlines.  Do some work to figure out if we
need to fall back to GNU inline syntax.

Fix some issues with GNU inline syntax.

a7ecf2646d iflag: automatically assign values, saner handling of CPU levels 
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.
