This patch moves the CommonArgs utilities into a location visible by the
Frontend Drivers, so that the Frontend Drivers may share option parsing
code with the Compiler Driver. This is useful when the Frontend Drivers
would like to verify that their incoming options are well-formed and
also not reinvent the option parsing wheel.
We already see code in the Clang/Flang Drivers that is parsing and
verifying its incoming options. E.g. OPT_ffp_contract. This option is
parsed in the Compiler Driver, Clang Driver, and Flang Driver, all with
slightly different parsing code. It would be nice if the Frontend
Drivers were not required to duplicate this Compiler Driver code. That
way there is no/low maintenance burden on keeping all these parsing
functions in sync.
Along those lines, the Frontend Drivers will now have a useful mechanism
to verify their incoming options are well-formed. Currently, the
Frontend Drivers trust that the Compiler Driver is not passing back junk
in some cases. The Language Drivers may even accept junk with no error
at all. E.g.:
`clang -cc1 -mprefer-vector-width=junk test.c'
With this patch, we'll now be able to tighten up incomming options to
the Frontend drivers in a lightweight way.

These are identified by misc-include-cleaner. I've filtered out those
that break builds. Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.
Using a relative path name for the shared library name was causing the
side deck name to be incorrect. Fixed the code by using the
`replace_exentsion()` function.
Since C++14 has been released for about nine years and most standard
libraries have implemented sized deallocation functions, it's time to
make this feature default again.
This is another try of https://reviews.llvm.org/D112921.
The original commit cf5a8b4 was reverted by 2e5035a due to some
