Remove REAL_VALUE_FROM_CONST_DOUBLE

To maintain symmetry after the previous removal of
CONST_DOUBLE_FROM_REAL_VALUE, this patch also gets rid of
REAL_VALUE_FROM_CONST_DOUBLE.  All the macro did was copy the
contents of CONST_DOUBLE_REAL_VALUE into a temporary real_value
structure.  In many cases there was no need for this temporary
and we could simply use the CONST_DOUBLE_REAL_VALUE directly.
For that reason this patch is less automatic than the others.

Bootstrapped & regression-tested on x86_64-linux-gnu.  Also tested by
building one target per CPU directory and checking that there were
no new warnings and no changes in testsuite output at -O2.
