Richard B suggested we should replace dconsthalf etc. with
dconst<1, 2> (). When I tried that, the extra comma caused problems
with some lingering uses of the old target macros for handling reals
(e.g. REAL_ARITHMETIC instead of real_arithmetic), since the constant
was then treated as two macro parameters. It would have been possible
to add an extra level of brackets to avoid this, but I thought I might
as well take the opportunity to remove the macros instead. (Note that
I'm only removing macros that caused a problem directly, or are closely
related to ones that did.)
This first patch replaces REAL_VALUES_EQUAL with a real_equal function.
The prototype is the same as for real_identical, which has already
undergone a half-transition in this direction.
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.

This renames the gimple_statement_base struct to gimple removes the
typedef of gimple_statement_base * to gimple, and then adjusts all of
the places that use the type.
gcc/ChangeLog:
2015-09-19 Trevor Saunders <tbsaunde@tbsaunde.org>
* coretypes.h (gimple): Change typedef to be a forward
declaration.
* gimple.h (gimple_statement_base): rename to gimple.
* (all functions and types using gimple): Adjust.
* *.[ch]: Likewise.
