libstdc++: Define <bits/functexcept.h> functions for freestanding [PR107135]

We don't compile src/c++11/functexcept.cc for freestanding, so just
define the functions used by freestanding entities as inline calls to
std::terminate.

libstdc++-v3/ChangeLog:

	PR libstdc++/107135
	* include/bits/functexcept.h [!_GLIBCXX_HOSTED]
	(__throw_invalid_argument, __throw_out_of_range)
	(__throw_out_of_range_fmt, __throw_runtime_error)
	(__throw_overflow_error): Define inline.
	* include/std/bitset (_M_copy_from_ptr) [!_GLIBCXX_HOSTED]:
	Replace __builtin_abort with __throw_invalid_argument.
