Hide alt_dump_file within dumpfile.c
This patch removes alt_dump_file from dumpfile.h, making it static
within dumpfile.c. This allows for changing how -fopt-info is
implemented, and potentially adding other kinds of dump target, such
as remarks or optimization records.
Doing so requires changing the implementation of dump_enabled_p, so
the patch changes this to a simple lookup of a boolean global, which
is updated any time dump_file or alt_dump_file change.

* cgraph.c (cgraph_node::get_body): Replace assignments to
"dump_file" with calls to set_dump_file.

PR c++/86320 - memory-hog with std::array of pair
* typeck2.c (process_init_constructor_array): Only compute a
constant initializer once.
In this PR, we have a large std::array of pairs. Since the C array is
wrapped in a class we don't go to build_vec_init, so we end up with
digest_init wanting to build up the element initializer for each element of
the array.
In the more general case, like 80272, we have a data structure problem: we
don't currently have a good way of expressing the same dynamic
initialization of many elements within a CONSTRUCTOR. RANGE_EXPR probably
ought to work, but will need more work at genericize or gimplify time.
But in this case, the initialization for each element reduces to constant
0, so we don't even need to add anything to the CONSTRUCTOR. We just need
to realize that if the initializer for one element is 0, the others will be
as well, and we don't need to iterate over the whole array.
For the trunk, I also use a RANGE_EXPR to handle constant initialization by
a value other than 0.

When the std::pair constructors got more complex to handle, it aggravated a
preexisting algorithmic problem in template overload resolution:
As part of template argument deduction in a call, once we've deduced all
the template arguments we can but before we substitute them to form an
actual declaration, for any function parameters that don't involve template
parameters we need to check that it's possible to convert the argument to
the parameter type (wg21.link/cwg1391).
As a result, we end up calculating the conversion twice: once here, and
then again in add_function_candidate as part of normal overload resolution.
Normally this isn't a big deal, but when the argument is a multiply-nested
initializer list, doubling the conversion processing at each level leads to
combinatorial explosion.
The patch for trunk avoids the duplication by remembering the conversion we
calculate at deduction time and then reusing it in overload resolution
rather than calculating it again.

runtime: use #ifdef instead of #if for USING_SPLIT_STACK
USING_SPLIT_STACK is configured as defined/undefined, not 0/1.
Most of the places test USING_SPLIT_STACK with #ifdef, with a
few exceptions. This CL fixes the exceptions.
