b07383ead1 [gsl_util] Update narrow_cast to use std::forward 
* Update narrow_cast to use std::forward

Based on [F19](https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#f19-for-forward-parameters-pass-by-tp-and-only-stdforward-the-parameter), I believe `gsl::narrow_cast` should be implemented using forward semantics.

* Fix for VS 2013

1e95421889 [#392] Don't install tests 
'make install' should install the GSL library (ie. the headers),
not the tests.

It still installs the UnitTest++ headers, but that will be more
complex to fix, as GSL just imports UnitTest++ as a git submodule,
and the install command propagates down to UnitTest++'s
CMakeLists.txt.

9e055be659 Fix compilation issues with Cygwin 
Cygwin recently did an update that broken string_span again. The original update had to provide a custom strnlen function because Cygwin doesn't implement this (it's a non-std extension). We never added wchar_t support, and the Cygwin update now breaks on exactly this. This patch provides the missing wchar_t.

4b29878d70 Add branch prediction to Ensures / Expects 
We should be using branch prediction on asserts as these conditions are known to be unlikely, therefore we should be optimizing the likely case. These macros are similar to what the Linux kernel uses. Not really sure what Visual Studio does so at the moment these are disabled for VS.

67717ea6ae [multi_span] Fix UB hack in static_bounds::operator= 
* Make BoundsRanges<dynamic_range, ...>::m_bound non-const and private

* Remove various defaulted copy constructor/assignment declarations from BoundsRanges specializations whose only effect is to needlessly suppress the generation of moves

* Remove the hackish static_bounds::operator=(const static_bounds&). The implicitly generated default is now sufficient

55b232dde4 Issue: #329 
This is my best attempt at fixing the issues raised by @gdr-at-ms while supporting VS2013, VS2015, providing shorter syntax than the static_cast and giving developer meaningful errors when they do the wrong thing.

95bbaa1ec2 Added to_byte method for issue #329 
I have added the to_byte method and updated the unit tests.

This gives slightly nicer syntax than static_cast, is better than the
c-style cast used in the unit test.
