i386: Check invalid (%dx) usage
(%dx) isn't a valid memory address in any modes. It is used as a special
memory operand for input/output port address in AT&T syntax and should
only be used with input/output instructions. Update i386_att_operand to
set i.input_output_operand to true for (%dx) and issue an error if (%dx)
is used with non-input/output instructions.
PR gas/29751
* config/tc-i386.c (_i386_insn): Add input_output_operand.
(md_assemble): Issue an error if input/output memory operand is
used with non-input/output instructions.
(i386_att_operand): Set i.input_output_operand to true for
(%dx).
* testsuite/gas/i386/inval.l: Updated.
* testsuite/gas/i386/x86-64-inval.l: Likewise.
* testsuite/gas/i386/inval.s: Add tests for invalid (%dx) usage.
* testsuite/gas/i386/x86-64-inval.s: Likewise.
