Subject: [PATCH] libstdc++: Fix test assumptions on long and long double

Expect that long might not fit into the long double mantissa bits.

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

libstdc++-v3/ChangeLog:

	* testsuite/experimental/simd/tests/operator_cvt.cc: Make long
	double <-> (u)long conversion tests conditional on sizeof(long
	double) and sizeof(long).
