This patch replaces all uses of CONST_DOUBLE_FROM_REAL_VALUE with the already-existing const_double_from_real_value. 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. gcc/ * real.h (CONST_DOUBLE_ATOF): Use const_double_from_real_value instead of CONST_DOUBLE_FROM_REAL_VALUE.

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.

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.

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.
