Allow real_format to be passed to more real.h functions

Most real.h routines used machine modes to specify the format of
an operation and converted that to a float_format * internally.
Some also had alternative versions that accepted a float_format *.

In an upcoming patch it seemed more convenient for the callers
I was adding to use float_format directly, since the callers need
to examine the format themselves for other reasons.  This patch
therefore replaces the machine_mode arguments with a new class that
allows both machine modes and float_format pointers to be used.

Tested on x86_64-linux-gnu, arm-linux-gnueabi and aarch64-linux-gnu.

rs6000: Save the PIC reg when needed

The PIC reg (r30) needs to be saved whenever the prologue sets it up,
not just if it is used elsewhere in the function.  Without this patch
the prologue for such a function will modify r30 without saving it
first, leading to disaster back in its callers.  This happened in the
testsuite for -m32 libgfortran and libstdc++, bootstrapped with -mlra,
many hundred times.

Remove redundant variable from tree-call-cdce.c

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.
