gather bbs and conditions in a single walk through dominators

Clean up the function to build scop's basic blocks and the function
that gathers the conditions under which a basic block is executed.  We remove
one traversal of the dominator tree.

This refactoring was triggered by the need of a vec<bb> of all the basic blocks
in a region.  We will use that vector in a patch that removes the out-of-ssa
translation of scalar dependences: we will iterate through the basic blocks of a
region to record scalar dependences crossing bbs or going out of the region.

The patch passes bootstrap and regtest on x86_64-linux.

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.

Replace REAL_VALUES_EQUAL with real_equal

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.

Remove dead code

* match.c (gfc_match_common): Remove dead variable old_blank_common.

From-SVN: r228458

Fix fortran common-related error recovery ICE.

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.
