Add Z3 to system libraries list if enabled

Without this trying to link static LLVM libraries (built with Z3 enabled) fails because `llvm-config` doesn't print `-lz3`.
We are already using this patch at MSYS2:

Update UnwindPlan dump to list if it is a trap handler func; also Command

Update the "image show-unwind" command output to show if the function
being shown is listed as a user-setting or platform trap handler.

Update the individual UnwindPlan dumps to show whether the unwind plan
is registered as a trap handler.

[llvm-lipo] Add support for bitcode files

A Mach-O universal binary may contain bitcode as a slice.
This diff adds proper handling of such binaries to llvm-lipo.

Test plan: make check-all
