For some targets (in my case VxWorks 5.5), libgcov does not compile due
to missing functions and macros such as getpid() and F_OK.
Incidentally, gcc/Makefile.in already contains comments such as
# Install gcov if it was compiled.
but there is no logic in place to actually allow gcov to not be
compiled.
So add an option for disabling build and install of libgcov and the
related host tools.

* 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.

Don't recalculate the conversion if it's already set.
(add_template_candidate_real): Allocate convs here.
(good_conversion, conv_flags): New.
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.
