[committed] libstdc++: Partially revert r11-9772-g6f8133689f4397 [PR105915]

[Jonathan Wakely <jwakely@redhat.com>]

I have done a partial revert on the gcc-11 branch to fix PR105915.

I'll also backport it to gcc-10 after testing finishes.

-- >8 --

The r11-9772-g6f8133689f4397 backport made two changes, but only one was
needed on the gcc-11 branch. The other should not have been backported,
and causes errors with clang. This removes the unwanted part.

libstdc++-v3/ChangeLog:

	PR libstdc++/105915
	* include/experimental/bits/fs_path.h (path::begin, path::end):
	Remove noexcept from declarations.
