Log:
[libcxx] [test] Fix string_view tests.
test/std/strings/string.view/string.view.ops/compare.pointer_size.pass.cpp
Passing -1 to size_t triggers signed/unsigned mismatch warnings because it's
a value-modifying conversion. Add static_cast<size_t> to soothe the compiler.
(This file refers to size_t unqualified.)
test/std/strings/string.view/string.view.ops/substr.pass.cpp
Add <algorithm> for std::min() and <stdexcept> for std::out_of_range.
N4618 21.4.2.4 [string.view.access]/1: "Requires: pos < size()."
/4: "[ Note: Unlike basic_string::operator[],
basic_string_view::operator[](size())
has undefined behavior instead of returning charT(). -end note ]"
Fixes D27633.
