The regex engine can't assume that SvSCREAM() remains set on its target.

Callers to the engine set REXEC_SCREAM in the flags when the target scalar is
studied, and the engine should use the study data. It's possible for embedded
code blocks to cause the target scalar to stop being studied. Hence the engine
needs to check for this, instead of simply assuming that the study data is
present and valid to read. This resolves #92696.
