[PATCH 07/11] libstdc++: Fix condition when AVX512F ldexp implementation is used

[Matthias Kretz]

From: Matthias Kretz <kretz@kde.org>

This improves codegen of ldexp if AVX512VL is available.

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

libstdc++-v3/ChangeLog:

	* include/experimental/bits/simd_x86.h (_S_ldexp): The AVX512F
	implementation doesn't require a _VecBltnBtmsk ABI tag, it
	requires either a 64-Byte input (in which case AVX512F must be
	available) or AVX512VL.
