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.

fixed-value.c was passing a fixed-point mode to the floating-point
real_2expN routine.  That didn't cause a problem in practice because
all real_2expN did was check for decimal float modes, but it triggered
a failure with an upcoming patch.

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