Fix various tool libraries not to link to clang's .a libraries and dylib
simultaneously. This may cause breakage, in particular through
duplicate command-line option declarations.

This reverts commit 97aa593a83 as it
causes problems (PR45453) https://reviews.llvm.org/D77574#1966321.
This additionally adds an explicit reference to FrontendOpenMP to
clang-tidy where ASTMatchers is used.
This is hopefully just a temporary solution. The dependence on
`FrontendOpenMP` from `ASTMatchers` should be handled by CMake
implicitly, not us explicitly.

The original check did break the green buildbot in the sanitizer build.
It took a while to redroduce and understand the issue.
There occured a stackoverflow while parsing the AST. The testcase with
256 case labels was the problem because each case label added another
stackframe. It seemed that the issue occured only in 'RelWithDebInfo' builds
and not in normal sanitizer builds.
To simplify the matchers the recognition for the different kinds of switch
statements has been moved into a seperate function and will not be done with
ASTMatchers. This is an attempt to reduce recursion and stacksize as well.
The new check removed this big testcase. Covering all possible values is still
implemented for bitfields and works there. The same logic on integer types
will lead to the issue.
Running it over LLVM gives the following results:

The address sanitizer found a stackoverflow with this patch.
There is no obvious fix. This patch will be reapplied when the problem
is found.

Summary:
This check searches for missing `else` branches in `if-else if`-chains and
missing `default` labels in `switch` statements, that use integers as condition.
It is very similar to -Wswitch, but concentrates on integers only, since enums are
already covered.
The option to warn for missing `else` branches is deactivated by default, since it is
very noise on larger code bases.
Running it on LLVM:
{F5354858} for default configuration
{F5354866} just for llvm/lib/Analysis/ScalarEvolution.cpp, the else-path checker is very noisy!
