This patch copies the string_view tests from the gcc repository (commit
b427286632d7).
${gcc}/libstdc++-v3/testsuite/21_strings/basic_string_view ->
${binutils-gdb}/gdb/unittests/basic_string_view
The local modifications are done in the following patch, so that it's
easier to review them.

To: gdb-patches; +Cc: Simon Marchi
We had a few times the need for a data structure that does essentially
what C++17's std::string_view does, which is to give an std::string-like
interface (only the read-only operations) to an arbitrary character
buffer.
This patch adapts the files copied from libstdc++ by the previous patch
to integrate them with GDB. Here's a summary of the changes:
* Remove things related to wstring_view, u16string_view and
u32string_view (I don't think we need them, but we can always add them
later).
* Remove usages of _GLIBCXX_BEGIN_NAMESPACE_VERSION and
_GLIBCXX_END_NAMESPACE_VERSION.
* Put the code in the gdb namespace. I had to add a few "std::" in
front of std type usages.
* Add a constructor that builds a string_view from an std::string, so
that we can pass strings to string_view parameters seamlessly.
Normally, that's handled by "operator __sv_type" in the std::string
declaration, but it only exists when building with c++17.
* Change __throw_out_of_range_fmt() for error().
* Make gdb::string_view and alias of std::string_view when building
with >= c++17.
* Remove a bunch of constexpr, because they are not valid in c++11
(e.g. they are not a single return line).
* Use std::common_type<_Tp>::type instead of std::common_type_t<_Tp>,
because c++11 doesn't have the later.
* Remove the #pragma GCC system_header, since that silences some
warnings that we might want to have if we're doing something not
correctly.
* GCC complains about us defining the ""sv user-defined literal,
because user code is supposed to use suffixes that begin with _.
However, we only use that code with c++ < 17, where we know the sv
literal is not defined. Recent GCCs allow turning off the warning
(-Wliteral-suffix), but gcc 4.8.4 (what the GCC compile farm ARM
builders have) don't have a way to silence this warning. The only way
I found was to add back #pragma GCC system_header, but at least I
could add it at the very end of the file. The pragma only makes the
rest of the file (what follows it) part of a system header, so the
code above should not be considered a system header.
The string_view class in cli/cli-script.c is removed and its usage
replaced with the new gdb::string_view.
gdb/ChangeLog:
* common/string_view.h: Remove libstdc++ implementation details,
adjust to gdb reality.
* common/string_view.tcc: Likewise.
* cli/cli-script.c (struct string_view): Remove.
(user_args) <m_args>: Change element type to gdb::string_view.
(user_args::insert_args): Adjust.
