[PATCH, i386]: Fix PR39897

[Uros Bizjak]

Hello!

Attached patch reverts %z handling of HImode operands back to previous
(wrong) state until better fix is found. Unfortunately, integer and
x87 operators don't agree which suffix to use for integer operands.

2009-04-25  Uros Bizjak  <ubizjak@gmail.com>

	PR target/39897
	* config/i386/i386.c (print_operand) ['z']: Revert handling of
	HImode operands.

Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline.

Uros.
