Record::getValueAsString returns a stringref to an interned
string (apparently had been changed since most of tablegen was
written). In this patch, I audited the usage of getValueAsString
to find places where we can trivially stop storing 'std::string' and instead
keep the stringref.

There was one instance where an unnecessary 'stringstream' was being used,
so that has been removed as well to unblock the stringref replacing string fix.

Typically we don't use the stringstream, so instead use
raw_string_stream.  Additionally, the dependent function
changed to use raw_ostream.

Attributes in the docs were previously sorted (apparently)
by the attribute name, so AnyX86Interrupt ended up being the
first one, rather than in a meaningful place. This resulted in the
4 'interrupt' titled sections being all in different places.

This replaces it with a naive alphabetical sort (case sensitive, underscore
and special characters first, etc).

Add -f[no-]double-square-bracket-attributes as new driver options to control use of [[]] attributes in all language modes. This is the initial implementation of WG14 N2165, which is a proposal to add [[]] attributes to C2x, but also allows you to enable these attributes in C++98, or disable them in C++11 or later.

At the moment if LLVM_BUILD_INSTRUMENTED is set to True 
one has to set LLVM_PROFTDATA even if it's not really used 
(because of message(FATAL_ERROR ...)). 
Building the instrumented version of Clang can be useful even if 
one doesn't plan to build the target generate-profdata
(currently that target would only compile utils/perf-training/cxx/hello_world.cpp).
For example, one can run the instrumented version of Clang 
via a separate build system against a different codebase, 
collect/analyze the profiles and merge them by llvm-profdata later.

Summary:
We don't want to autocomplete flags whose Flags class has `NoDriverOption` when argv[1] is not `-cc1`.

Another idea for this implementation is to make --autocomplete a cc1
option and handle it in clang Frontend, by porting --autocomplete
handler from Driver to Frontend, so that we can handle Driver options
and CC1 options in unified manner.
