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_builtin_logb and fold_builtin_significand now only handle
constant arguments, so this patch renames them to fold_const...,
to match fold_const_builtin_pow. The idea is to differentiate
constant-only folds so that they can be moved to a const_binop-like
function in future.
The functions also had some unnecessary calls to STRIP_NOPS, which
I think are left over from code that has already moved to match.pd.

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.
