tcg/i386: Split out target constraints to tcg-target-con-str.h
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.
