Fix ICE due to "combine" creating unreachable EH blocks (PR target/88861)
PR target/88861 reports an ICE in "ce2" due to an unreachable
basic block.
The block becomes unreachable in "combine" when delete_noop_moves
deletes an insn with a REG_EH_REGION, deleting the EH edge, the
only edge leading to the basic block.
Normally, rest_of_handle_combine would call cleanup_cfg, deleting
unreachable blocks, if combine_instructions returns true, and
combine_instructions does return true for some cases of edge-removal,
but it doesn't for this case, leading to the ICE.
This patch updates delete_noop_moves so that it returns true if
it deletes any edges, and passes that through to combine_instructions,
so that it too will return true if any edges were deleted, ensuring that
cleanup_cfg will be called by rest_of_handle_combine for this case,
deleting the now-unreachable block, and fixing the ICE.

__builtin_<add/sub>_overflow issues on AArch64 (redux)
Further investigation showed that my previous patch for this issue was
still incomplete.
The problem stemmed from what I suspect was a mis-understanding of the
way overflow is calculated on aarch64 when values are subtracted (and
hence in comparisons). In this case, unlike addition, the carry flag
is /cleared/ if there is overflow (technically, underflow) and set
when that does not happen. This patch clears up this issue by using
CCmode for all subtractive operations (this can fully describe the
normal overflow conditions without anything particularly fancy);
clears up the way we express normal unsigned overflow using CC_Cmode
(the result of a sum is less than one of the operands) and adds a new
mode, CC_ADCmode to handle expressing overflow of an add-with-carry
operation, where the standard idiom is no-longer sufficient to
describe the overflow condition.

Lower sampling rate for autofdo bootstrap
autofdo create_gcov uses a lot of memory for large sample files.
Since gcc runs quite long the sample files generated during
the bootstrap are fairly ig.
Currently I can't even build make autoprofiledbootstrap on my system at
home because create_gcov needs more than 12GB and runs out of memory.
This should probably be fixed in create_gcov, but for now
lowering the sampling rate works well enough for me. The bootstrap
run is long enough that it gets good enough data in any case.

[nvptx] Verify dimension limits after applying defaults
There's a problem in oacc_validate_dims that when f.i. the worker dimension
is set using -fopenacc-dim=:32, and the vector_length is set using a
"vector_length (128)" clause, the compiler combines, accepts and emits the
values, while the combination of the two is invalid.
The reason for this is that while oacc_validate_dims validates the dimensions
using targetm.goacc.validate_dims before applying default or minimum values,
it does not do so afterwards.
Work around this in the nvptx port by applying the defaults from
oacc_default_dims at the end of nvptx_goacc_validate_dims_1, as
oacc_validate_dims would do it, and then apply the dimensions limits.

P0357R3 reference_wrapper for incomplete types
This patch implements the C++2a proposal to allow incomplete types in
std::reference_wrapper, which was previously undefined.
The change cannot be implemented for earlier standards, because prior to
C++2a std::reference_wrapper has a weak result type, so must inspect the
template argument to see if it defines a nested result_type member. That
is deprecated (but still required) in C++17, and removed from C++2a.
The removal of the base class from reference_wrapper is a potential ABI
change, as it could alter the layout of a type which derives from
reference_wrapper<T> and from an empty type with _Weak_result_type<T> as
a base class. Previously the repeated _Weak_result_type<T> base class
would have prevented the empty base-class optimization, but if
reference_wrapper<T> no longer derives from it, the empty class could be
placed at the same address as the reference_wrapper<T> base. In
practice, the only types which derive from _Weak_result_type or from
_Reference_wrapper_base_memfun or any of its base classes are non-empty
types defined in libstdc++: std::reference_wrapper, std::function, and
std::_Bind. As they are non-empty types, they are not eligible for EBO
anyway.

adding mark_rvalue_use calls to build_new_op_1, but it seems appropriate to
have them in cp_fold_maybe_rvalue when we know we're trying to produce an
rvalue.
The change to mark_use is for a related issue: when we change the operand of
the location wrapper from VAR_DECL to INTEGER_CST, we need the TREE_CODE of
the location wrapper to change as well, from VIEW_CONVERT_EXPR to
NON_LVALUE_EXPR.
