Before, the CLANG_DEFAULT_LINKER cmake option was a global override for
the linker that shall be used on all toolchains. The linker binary
specified that way may not be available on toolchains with custom
linkers. Eg, the only linker for VE is named 'nld' - any other linker
invalidates the toolchain.
This patch removes the hard override and instead lets the generic
toolchain implementation default to CLANG_DEFAULT_LINKER. Toolchains
can now deviate with a custom linker name or deliberatly default to
CLANG_DEFAULT_LINKER.

The CLANG_DEFAULT_LINKER flag overrides the default toolchain linker.
VE strictly requires 'nld' to be the default linker. This causes a test
failure in test/Driver/ve-toolchain.cpp when configured with
CLANG_DEFAULT_LINKER!=ld
Failure in clang-ppc64le-rhel
(https://lab.llvm.org/buildbot/#/builders/57/builds/12628)
Until default linker selection with CLANG_DEFAULT_LINKER!=ld is fixed
proper, we manually specify '-fuse-ld=ld' (ie the toolchain default
linker) in the ve-toolchain tests.
This patch enables marshalling of the exception model options while enforcing their mutual exclusivity. The clang driver interface remains the same, this only affects the cc1 command line.
Depends on D93215.

Optimize toolchain regression test for VE by removing not a useful test
(-fuse-init-array test) and merge several tests to one test which checks
default behavior of driver. Also add sysroot to reduce conflicts.
These are suggested in https://reviews.llvm.org/D92996.
Thank you so much.

Remove explicitly declared -faddrsig and -fnoaddrsig option tests
since those are already tested in addrsig.c. We test only the implicit
behavior of VE driver.
This is suggested in https://reviews.llvm.org/D92386. Thanks.

It should specify --sysroot to test the paths of crt1.o/crti.o/crtbegin.o.
For a user who enable VE but do not actually have VE sysroot,
the "nld" command line will have bare "crt1.o" "crti.o" ... "crtbegin.o"
We have a plan to add libcxx and libcxxabi for VE. In order to do so,
we need to compile cxx source code with bootstarapped header files.
This patch adds such expected path to make clang++ work, at least
not crash at the startup. Add regression test for that, also.
