[ob] Fix new value-related failures in i386-sse.exp

[Daniel Jacobowitz]

Some time in the last week or so, i386-sse.exp started failing.  The problem
is:

set var $xmm0.v4_float[0] = 0 + 10
Value being assigned to is no longer active.
(gdb) PASS: gdb.arch/i386-sse.exp: set %xmm0

There's a couple more places where we copy VALUE_LVAL, of something which
might be lval_register, without copying VALUE_FRAME_ID.  Patch tested on
i386-pc-linux-gnu; committed as obvious.

	* valarith.c (value_subscript): Copy VALUE_FRAME_ID.
	(value_subscripted_rvalue): Likewise.
	* valops.c (search_struct_field, value_slice): Likewise.
