Subject: libstdc++: Make coroutine_handle<_Promise>::from_address() noexcept [PR 99021]
X-Git-Tag: releases/gcc-10.3.0~311

libstdc++: Make coroutine_handle<_Promise>::from_address() noexcept [PR 99021]

The coroutine_handle<void>::from_address(void*) version is already
noexcept, and they do the same thing. Make them consistent.

libstdc++-v3/ChangeLog:

	PR libstdc++/99021
	* include/std/coroutine (coroutine_handle<P>::from_address): Add
	noexcept.

(cherry picked from commit 26a3f288f1895a8c061c0458590542a3d2ee796a)
