Implement C11 excess precision semantics for conversions (PR c/82071).
C11 semantics for excess precision (from N1531) are that an implicit
conversion (from the usual arithmetic conversions, not by assignment)
from integer to floating point has a result in the corresponding
evaluation format of that floating-point type, so possibly with excess
precision (whereas a cast or conversion by assignment from integer to
floating point must produce a value without excess range or precision,
as always). This patch makes GCC support those semantics if
flag_isoc11 (which in turn means that conditional expressions need to
support generating a result with excess precision even if neither
operand had excess precision).
C99 is less than entirely clear in this regard, but my reading as
outlined at <https://gcc.gnu.org/ml/gcc-patches/2008-11/msg00105.html>
is that the results of conversions from integer to floating-point
types are always expected to be representable in the target type
without excess precision, and this patch conservatively keeps these
semantics for pre-C11 (i.e. if an older standard is explicitly
selected).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

[include] Add macro DISABLE_COPY_AND_ASSIGN
We have many classes that copy cotr and assignment operator are deleted
in different projects, gcc, gdb and gold. So this patch adds a macro
to do this, and replace these existing mechanical code with macro
DISABLE_COPY_AND_ASSIGN.
The patch was posted in gdb-patches,
https://sourceware.org/ml/gdb-patches/2017-07/msg00254.html but we
think it is better to put this macro in include/ansidecl.h so that
other projects can use it too.

Add LOOP_VINFO_MAX_VECT_FACTOR
Epilogue vectorisation uses the vectorisation factor of the main loop
as the maximum vectorisation factor allowed for correctness. That makes
sense as a conservatively correct value, since the chosen vectorisation
factor will be strictly less than that anyway. However, once the VF
itself becomes variable, it's easier to carry across the original

Store VECTOR_CST_NELTS directly in tree_node
Previously VECTOR_CST_NELTS (t) read the number of elements from
TYPE_VECTOR_SUBPARTS (TREE_TYPE (t)). There were two ways of handling
this with variable TYPE_VECTOR_SUBPARTS: either forcibly convert the
number to a constant (which is doable) or store the number directly
in the VECTOR_CST. The latter seemed better, since it involves less
pointer chasing and since the tree_node u field is otherwise unused
for VECTOR_CST. It would still be easy to switch to the former in
future if we need to free up the field for someting else.
The patch also changes various bits of VECTOR_CST code to use
VECTOR_CST_NELTS instead of TYPE_VECTOR_SUBPARTS when iterating
over VECTOR_CST_ELTs. Also, when the two are checked for equality,
the patch prefers to read VECTOR_CST_NELTS (which must be constant)
and check against TYPE_VECTOR_SUBPARTS, instead of the other way
around.

compiler, runtime: simplify select and channel operations
In preparation for upgrading libgo to the 1.9 release, this
approximately incorporates https://golang.org/cl/37661 and
https://golang.org/cl/38351.
CL 37661 changed the gc compiler such that the select statement simply
returns an integer which is then used as the argument for a switch.
Since gccgo already worked that way, this just adjusts the switch code
to look like the gc switch code by removing the explicit case index
expression and calculating it from the order of calls to selectsend,
selectrecv, and selectdefault.
CL 38351 simplifies the channel code by not passing the unused channel
type descriptor pointer.

Turn SECONDARY_MEMORY_NEEDED_MODE into a target hook
This includes a change to LRA. Previously the code was:
if (sclass == NO_REGS && dclass == NO_REGS)
return false;
#ifdef SECONDARY_MEMORY_NEEDED
if (SECONDARY_MEMORY_NEEDED (sclass, dclass, GET_MODE (src))
#ifdef SECONDARY_MEMORY_NEEDED_MODE
&& ((sclass != NO_REGS && dclass != NO_REGS)
|| GET_MODE (src) != SECONDARY_MEMORY_NEEDED_MODE (GET_MODE (src)))
#endif
)
{
*sec_mem_p = true;
return false;
}
#endif
in which the positioning of the second ifdef meant that defining
SECONDARY_MEMORY_NEEDED_MODE to its default value was not a no-op:
without a definition, we would consider using secondary reloads for
mem<-reg and reg<-mem reloads even if the secondary memory has the
same mode as the original mem, while defining it would avoid this.
The latter behaviour seems correct.
The default is different for reload and LRA. For LRA the default is
to use the original mode, while reload promotes smaller-than-word
integral modes to word mode:
if (GET_MODE_BITSIZE (mode) < BITS_PER_WORD && INTEGRAL_MODE_P (mode))
mode = mode_for_size (BITS_PER_WORD,
GET_MODE_CLASS (mode), 0).require ();
Some of the ports that have switched to LRA seemed to have
SECONDARY_MEMORY_NEEDED_MDOEs based on the old reload definition,
and still referred to the reload.c:get_secondary_mem function in
the comments. The patch just keeps them as-is.

The `ld1r` was needed when this should have generated

[testsuite/ARM] Fix coprocessor intrinsic test failures on ARMv8-A
Coprocessor intrinsic tests in gcc.target/arm/acle test whether
__ARM_FEATURE_COPROC has the right bit defined before calling the
intrinsic. This allows to test both the correct setting of that macro
and the availability and correct working of the intrinsic. However the
__ARM_FEATURE_COPROC macro is no longer defined for ARMv8-A since
r249399.
This patch changes the testcases to skip that test for ARMv8-A and
ARMv8-R targets. It also fixes some irregularity in the coprocessor
effective targets:
- add ldcl and stcl to the list of instructions listed as guarded by
arm_coproc1_ok
- enable tests guarded by arm_coproc2_ok, arm_coproc3_ok and
arm_coproc4_ok for Thumb-2 capable targets but disable for Thumb-1
targets.
