Subject: [PATCH] libstdc++: Fix -Wsign-compare issue

Signed-off-by: Matthias Kretz <m.kretz@gsi.de>

libstdc++-v3/ChangeLog:

	* include/experimental/bits/simd_builtin.h (_S_set): Compare as
	int. The actual range of these indexes is very small.

(cherry picked from commit ffa39f7120f6e83a567d7a83ff4437f6b41036ea)
