These are identical to the 'r' constraint.

The opcodes always exist, regardless of whether or not they
are enabled. Remove the unnecessary ifdefs.

Rather than check the type when filling in the constraint,
check it when matching the constant. This removes the only
use of the type argument to target_parse_constraint.

Create symbolic constants for all low-byte-addressable
and second-byte-addressable registers. Create a symbol
for the registers that need reserving for softmmu.
There is no functional change for 's', as this letter is
only used for i386. The BYTEL name is correct for the
action we wish from the constraint.

This eliminates the target-specific function target_parse_constraint
and folds it into the single caller, process_op_defs. Since this is
done directly into the switch statement, duplicates are compilation
errors rather than silently ignored at runtime.
