Properly handle -fno-plt in ix86_expand_call
prepare_call_address in calls.c is the wrong place to handle -fno-plt.
We shoudn't force function address into register and hope that load
function address via GOT and indirect call via register will be folded
into indirect call via GOT, which doesn't always happen. Also non-PIC
case can only be handled in backend. Instead, backend should expand
external function call into indirect call via GOT for -fno-plt.
This patch reverts -fno-plt in prepare_call_address and handles it in
ix86_expand_call. Other backends may need similar changes to support
-fno-plt. Alternately, we can introduce a target hook to indicate
whether an external function should be called via register for -fno-plt
so that i386 backend can disable it in prepare_call_address.

Fold comparisons between sqrt and zero
The expression:
signbit(sqrt(x))
is always 0 for -ffast-math. The signbit fold first converts it to:
sqrt(x) < 0
and whether we realise that this is false depends on a race between two
folders: the sqrt comparison folder, which wants to convert it to
x < 0*0
and the generic tree_expr_nonnegative_p rule for ... < 0, which would
give the hoped-for 0.
The sqrt code already handles comparisons with negative values specially,
so this patch simply extends that idea to comparisons with zero.

Don't create SSA names until in SSA form
An upcoming patch adds a fold from hypot(x,x) to fabs(x)*sqrt(2).
This is unusual in that it could trigger in the gimplifier but would
require new SSA names to be created. This patch makes sure that we
use the usual:
if (gimple_in_ssa_p (cfun))
res = make_ssa_name (type);
else
res = create_tmp_reg (type);
formula to cope with cases where we're not yet in SSA form.

While the sed commands are run under LC_ALL=C, the two sort commands are
not, and they end up producing unexpected output (for the test). Once we
run both under LC_ALL=C, the check passes. While we're here, we can also
combine latter the `sort|uniq` into `sort -u` to match the earlier code.
