[SLP]Disable scheduling of insertelements.

There is no need to schedule insertelement instructions. The compiler
did not schedule them before it started support their vectorization and
it should not do it after. We pre-schedule them manually when finding

[clang-cl] Add /permissive and /permissive-

This patch adds the command line options /permissive and /permissive- to clang-cl. These flags are used in MSVC to enable various /Zc language conformance options at once. In particular, /permissive is used to enable the various non standard behaviour of MSVC, while /permissive- is the opposite.

When either of two command lines are specified they are simply expanded to the various underlying /Zc options. In particular when /permissive is passed it currently expands to:

/Zc:twoPhase- (disable two phase lookup)
-fno-operator-names (disable C++ operator keywords)
/permissive- expands to the opposites of these flags + /Zc:strictStrings (/Zc:strictStrings- does not currently exist). In the future, if any more MSVC workarounds are ever added they can easily be added to the expansion. One is also able to override settings done by permissive. Specifying /permissive- /Zc:twoPhase- will apply the settings from permissive minus, but disables two phase lookup.

Motivation for this patch was mainly parity with MSVC as well as compatibility with Windows SDK headers. The /permissive page from MSVC documents various workarounds that have to be done for the Windows SDK headers [1], when MSVC is used with /permissive-. In these, Microsoft often recommends simply compiling with /permissive for the specified source files. Since some of these also apply to clang-cl (which acts like /permissive- by default mostly), and some are currently implemented as "hacks" within clang that I'd like to remove, adding /permissive and /permissive- to be in full parity with MSVC and Microsofts documentation made sense to me.

[clang-tidy] performance-unnecessary-copy-initialization: Remove the complete statement when the copied variable is unused.

It is not useful to keep the statement around and can lead to compiler
warnings when -Wall (-Wunused-variable specifically) turned on.

I found the documentation of the various CMake variables difficult to
navigate, because they are unsorted. I can see they've grown
organically with new clusters of somewhat-related options, but the
