libstdc++: Do not use assume attribute for Clang [PR112467]

Browse Source 
Clang has an 'assume' attribute, but it's a function attribute not a
statement attribute. The recently-added use of the statement form causes
an error with Clang.

libstdc++-v3/ChangeLog:

	PR libstdc++/112467
	* include/bits/stl_bvector.h (_M_assume_normalized): Do not use
	statement form of assume attribute for Clang.
