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.

Remove remaining uses of REAL_VALUES_IDENTICAL
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
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.

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.

[AArch64] Use default_elf_asm_named_section instead of special cased hook
Hi,
The hook for TARGET_ASM_NAMED_SECTION was defined separately in
the backend around the time frame for GCC 4.7 under the assumption
that '@' would be used as a comment character in the binutils port.
This was indeed true in versions of the AArch64 port that never made it
into the FSF tree. However this practice was killed
before the binutils port made it upstream. Doing archaeology into
various revisions including the first commit of upstream binutils,
talking to Marcus about the history of this and actually testing the
first commit of binutils, I can confidently say that the upstream binutils
port never had any use of '@' as a comment character for AArch64
However we never got rid of the special cased handling in
GCC and the duplication of code in the AArch64 backend.
This was found when I was playing with Virtual Table verification
on ARM and AArch64 and discovered ICEs which were similar but manifested
in different places begging the obvious question.
Tested on aarch64-none-elf with no regressions.
Ok to apply ?
