This patch improves the assertion message generated in 2
__gnu_debug::string constructors giving the assertion context thanks to
the __FUNCTION__ macro.

A change of mine to the strlen pass assumes that the strlen
argument points to an object of the correct type and does
not correctly handle GIMPLE where the argument has the wrong
type such as in:
extern char a[1][2];
n = strlen (*a);
where the strlen pass actually sees
n = strlen (a);

As spotted by the reporter of the bug, there is a small thinko at the end of
choose_multiplier whereby the (N + 1)th bit of the result is set when the
computed value is exactly 2**N. But it turns out that this case can never
actually happen given how the function is invoked in the compiler.
The following removes adding -lieee to the link command when -mieee-fp
is specified for GNU targets as suggested by Joseph in the PR. It doesn't
touch m32r so the fix may be incomplete depending on the C library used.
I've added a testcase that makes sure we can link but not functional

The intrinsic doesn't check for allowed conversions between scalar
types, so restore the std::is_constructible check.

This has been buggy for a while, but since we were implementing
the library triviality traits in terms of just the intrinsic since GCC 8,
not too many users ran into it. The bug has been worked around
in the library, but I'd rather have the intrinsic give the right
answer and not require the
