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

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.)

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,

Fixed by both adding the symbol to the common block list and setting

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

[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.

rs6000: Add "cannot_copy" attribute, use it (PR67788, PR67789)
After the shrink-wrapping patches the prologue will often be pushed
"deeper" into the function, which in turn means the software trace cache
pass will more often want to duplicate the basic block containing the
prologue. This caused failures for 32-bit SVR4 with -msecure-plt PIC.
This configuration uses the load_toc_v4_PIC_1 instruction, which creates
assembler labels without using the normal machinery for that. If now
the compiler decides to duplicate the insn, it will emit the same label
twice. Boom.
It isn't so easy to fix this to use labels the compiler knows about (let
alone test that properly). Instead, this patch wires up a "cannot_copy"
attribute to be used by TARGET_CANNOT_COPY_P, and sets that attribute on

Now that we have a valid SESE region, we can call the scev analysis in the same
