This test is rejected with a bogus "use of deleted function" error
starting with r225705 whereby convert_like_real/ck_base no longer
sets LOOKUP_ONLYCONVERTING for user_conv_p conversions. This does
not seem to be always correct. To recap, when we have something like
T t = x where T is a class type and the type of x is not T or derived
from T, we perform copy-initialization, something like:
1. choose a user-defined conversion to convert x to T, the result is
a prvalue,
2. use this prvalue to direct-initialize t.
In the second step, explicit constructors should be considered, since
we're direct-initializing. This is what r225705 fixed.
In this PR we are dealing with the first step, I think, where explicit
constructors should be skipped. [over.match.copy] says "The converting
constructors of T are candidate functions" which clearly eliminates
explicit constructors. But we also have to copy-initialize the argument
we are passing to such a converting constructor, and here we should
disregard explicit constructors too.
In this testcase we have
V v = m;
and we choose V::V(M) to convert m to V. But we wrongly choose
the explicit M::M<M&>(M&) to copy-initialize the argument; it's
a better match for a non-const lvalue than the implicit M::M(const M&)
but because it's explicit, we shouldn't use it.
When convert_like is processing the ck_user conversion -- the convfn is
V::V(M) -- it can see that cand->flags contains LOOKUP_ONLYCONVERTING,
but then when we're in build_over_call for this convfn, we have no way
to pass the flag to convert_like for the argument 'm', because convert_like
doesn't take flags. Fixed by creating a new conversion flag, copy_init_p,
set in ck_base/ck_rvalue to signal that explicit constructors should be
skipped.
LOOKUP_COPY_PARM looks relevant, but again, it's a LOOKUP_* flag, so
can't pass it to convert_like. DR 899 also seemed related, but that
deals with direct-init contexts only.

Fix a problem with the libffi testsuite using a method to determine the
compiler to use resulting in the tool being different from one the
library has been built with, and causing a catastrophic failure from the
inability to actually choose any compiler at all in a cross-compilation
configuration.
Address this problem by providing a DejaGNU configuration file defining
the compiler to use, via the CC_FOR_TARGET TCL variable, set from $CC by
autoconf, which will have all the required options set for the target
compiler to build executables in the environment configured, removing
failures like:

As the new testcase shows, it is not safe to assume we can optimize
a conditional store into an automatic non-addressable var, we can do it
only if we can prove that the unconditional load or store actually will
not be outside of the boundaries of the variable.
If the offset and size are constant, we can, but this is already all
checked in !tree_could_trap_p, otherwise we really need to check for
a dominating unconditional store, or for the specific case of automatic
non-addressable variables, it is enough if there is a dominating load
(that is what those 4 testcases have). tree-ssa-phiopt.c has some
infrastructure for this already, see the add_or_mark_expr method etc.,
but right now it handles only MEM_REFs with SSA_NAME first operand
and some integral offset. So, I think it can be for GCC11 extended
to handle other memory references, possibly up to just doing
get_inner_reference and hasing based on the base, offset expressions
and bit_offset and bit_size, and have also a special case that for
!TREE_ADDRESSABLE automatic variables it could ignore whether something
is a load or store because the local stack should be always writable.
But it feels way too dangerous to do this this late for GCC10, so this
patch just restricts the optimization to the safe case (where lhs doesn't
trap), and on Richi's request also ignores TREE_ADDRESSABLE bit if
flag_store_data_races, because my understanding the reason for
TREE_ADDRESSABLE check is that we want to avoid introducing
store data races (if address of an automatic var escapes, some other thread
could be accessing it concurrently).

In the testcase below, when grokfndecl processes the operator() decl for the
lambda inside the friend function foo, processing_template_decl is rightly 1,
but template_class_depth on the lambda's closure type incorrectly returns 0
instead of 1.
Since processing_template_decl > template_class_depth, this makes grokfndecl
think that the operator() has its own set of template arguments, and so we
attach the innermost set of constraints -- those belonging to struct l -- to the
operator() decl. We then get confused when checking constraints_satisfied_p on
the operator() because it doesn't have template information and yet has
constraints associated with it.
This patch fixes template_class_depth to return the correct template nesting
level in cases like these, in that when it hits a friend function it walks into
the DECL_FRIEND_CONTEXT of the friend rather than into the CP_DECL_CONTEXT.
