[SCCP] Avoid markConstant() in more places (#206494)

This extends the fix from 991455e69e93c0ce88e927eddd28a9ab34d1f8b2 to
two more places. In both of these, we can run into the same situation
where we first mark as constant with a vector that has poison values,
and then again without poison elements, resulting in an assertion
failure.

(An alternative would be to change markConstant() to allow calls with
different constant if the new constant is a vector that only refines
some previously poison elements?)

[analyzer] Rename z3 constraint manager backend to unsupported-z3 (#205370)

The Z3 constraint manager backend (selected via
-analyzer-constraints=z3) is unmaintained and known to crash on
real-world input. Rename the user-facing flag to unsupported-z3 and
reword its description so users see up front that the backend is
unsupported and crash-prone -- patches welcome, crash reports are not.

call and ObjFile creation. It's also preparation for handling hybrid

if olInit fails, it leaves liboffload in an inconsistent state (proper

seemingly unrelated test failures (e.g. the host device is missing).
This patch makes such tests fail immediately with a clear error message.
