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.

An upcoming patch adds a fold from hypot(x,x) to fabs(x)*sqrt(2).

libjava: fix locale handling when sorting JNI methods

When building under LANG=cs_CZ.UTF-8, the JNI method check fails:

/bin/bash ../../scripts/check_jni_methods.sh
Found a problem with the JNI methods declared and implemented.
(<) missing in implementation, (>) missing in header files
> Java_gnu_java_awt_peer_gtk_GtkClipboard_advertiseContent
> Java_gnu_java_awt_peer_gtk_GtkClipboard_initNativeState
... lots more ...

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.

Allow more complex call replacements in gimple-fold.c

An upcoming patch adds a match.pd rule that folds pow(pow(x,y),z)
to pow(x,y*z).  This fold can reuse the existing pow gimple statement
and simply replace the operands with x and y*z.  However, the y*z
itself requires a separate gimple statement and the code wasn't
prepared to handle that.
