* config/i386/i386.c (ix86_md_asm_adjust): If dest_mode is
GET_MODE (dest), is not QImode, using ZERO_EXTEND and dest is not
register_operand, force x into register before storing it into dest.
Formatting fix.

Started to ICE with r225122.  Shorter testcase:
void
foo (void)
{
  void *p = (void *) &p;
  __asm__ ("" : "=@ccng" (p) : "r" (1));
}
