i386: Align stack frame if argument is passed on stack

When a function call is removed, it may become a leaf function.  But if
argument may be passed on stack, we need to align the stack frame when
there is no tail call.

Tested on Linux/i686 and Linux/x86-64.

gcc/

	PR target/83330
	* config/i386/i386.c (ix86_compute_frame_layout): Align stack
	frame if argument is passed on stack.
