9a7897915e Minimize checking in subspan (#569)
* rewrite span subspan checks to help optimizations
* Removed checking pointer for null for subspans. We would never
  check pointer for null in between ptr and ptr+size in the
  original span, so there seems to be  no reason to do so for
  subspans, provided that the subspan's boundaries are ensured
  to be within the range of the original span's boundaries.

This change allows to simplify generated code, for example, to
remove 5 out of 9 branches in code generated from the following
by MSVC, and 4 out 8 branches in clang and gcc-generated code:

span<int> mysubspan(int* p, std::ptrdiff_t size, std::ptrdiff_t i)
{
  if (p != nullptr)
  {
    span<int> s = { p, size };
    return s.subspan(i);
  }

  return { nullptr };
}

Similar effects are achieved for dynamic subspans of static spans,
where in the following code we remove 2 out of 4 branchs in MSVC
and GCC-generated code:

int test_dynamic_subspan_of_static_span(std::ptrdiff_t i)
{
  int x[] = { 0,1,2,3,4,5 };
  span<int, 6> s = { x };
  auto subspan = s.subspan(i);
  return subspan.size();
}

4c5fdb541f Made string_span details::string_length() generic (Fix issue #542) (#543)
* Made string_span details::string_length() generic

removed overloads & specialized classes

Creating string_spans using `char16_t` and `char32_t` was not possible
without creating new specializations and function overloads.

This patch makes details::string_length() generic removing the need to
extend the overloads and specializations.

* added type aliases for string_span types char16_t and char32_t

* Added char16_t & char32_t overloads for ensure_z

* added string_span tests for char16_T & char32_t

* added zstring type aliases for char16_t & char32_t

* Added tests for char16_t & char31_t zstring and string_span types

* applies clang format to <gsl/string_span>

* Clang format tests/string_span_tests.cpp

* Removed ensure_z() overloads as they don't add functionality.

* Fixes issue with dereferencing operator issue #491 introduced in PR #513

dereferencing operator added in PR#513 returned a copy of the object
instead of reference to it.
Adding decltype(auto) as return type of operator* fixes this issue.

39902b6ec0 span_iterator: converting constructor isn't a copy constructor (#511)
Fixes #510.

* Constrain the converting constructor to not participate in overload resolution when IsConst is true, so that it is never a copy constructor.
* Use Default Member Initializers for span_iterator's data members so that the default constructor can be explicitly defaulted.
* Declare all members of span_iterator GSL_NOEXCEPT: they only throw when contract violations throw.
* Don't use & in operator-> since evil types may overload it.

c2f953f2eb Add value_type to span (#425)
* Add value_type to span

Currently I'm working on project which involves a lot of `span`s and mocking via Google Mock. Unfortunately a lot of standard matchers requires `value_type` type definition inside container which `gsl::span` lacks.

This pull request add `value_type` type definition inside `gsl::span`

* Strip cv from value_type of span and span_iterator
