[libcxx] Avoid spurious construction of valarray elements
...
Summary:
Currently libc++ implements some operations on valarray by using the
resize method. This method has a parameter with a default value.
Because of this, valarray may spuriously construct and destruct
objects of valarray's element type.
This patch fixes this issue and adds corresponding test cases.
