    analyzer: fix signal-handler registration location [PR95188]

    PR analyzer/95188 reports that diagnostics from
    -Wanalyzer-unsafe-call-within-signal-handler use the wrong
    source location when reporting the signal-handler registration
    event in the diagnostic_path.  The diagnostics erroneously use the
    location of the first stmt in the basic block containing the call
    to "signal", rather than that of the call itself.

    Fixed thusly.

    gcc/analyzer/ChangeLog:
            PR analyzer/95188
            * engine.cc (stmt_requires_new_enode_p): Split enodes before
            "signal" calls.

    gcc/testsuite/ChangeLog:
            PR analyzer/95188
            * gcc.dg/analyzer/signal-registration-loc.c: New test.
