commit bbe910e6e1140cb484a74911f3cea854cf9e7e2a

    Add noexcept to custom non-throwing new operators.
    
    Both libc++ and libstdc++ declare non-throwing new operators as
    noexcept and overloads must also be noexcept.  This fixes a
    -Wmissing-exception-spec warning with clang.
    
    gdb/ChangeLog:
    
    	* common/new-op.c (operator new): Mark 'noexcept'.
    	(operator new[]): Likewise.
