    • Replace REAL_VALUES_LESS with real_less · 8cb41028 
      This patch continues the removal of real-related macros by
replacing REAL_VALUES_LESS with real_less.

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.

    • Remove remaining uses of REAL_VALUES_IDENTICAL · 1a25c6b1 
      This patch continues the removal of real-related macros.
We already had both the old-style REAL_VALUES_IDENTICAL and the
new-style real_identical, so this patch replaces all remaining
uses of the former with the latter.

building one target per CPU directory and checking that there were
no new warnings and no changes in testsuite output at -O2.

    • Replace REAL_VALUES_EQUAL with real_equal · 624d31fe 
      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.

    • Fix fortran common-related error recovery ICE. · 2b3f52a2 
      Upon reverting a symbol in a common block (after throwing an error),
the compiler was ICEing because the symbol's common_block field was set,
but the symbol was not in the common block's list of symbols.

Fixed by both adding the symbol to the common block list and setting
the symbol's common_block field at the same time.
Furthermore, the gfc_add_in_common call is delayed and its result is
ignored, so that its error messages are ignored and the compiler has
the opportunity to give a better error message.
Another gfc_add_in_common call is added later during resolution
to emit again the missing errors.
