SandstromPLandClaude Opus 5.5 051dac94ee fix(relinker): find the PLT before the code in PS4 modules
FindSceCodeEnd looked for the PLT only after the last function of the
unwind table and failed with "PLT not found after the last unwind
function" otherwise. The libSceFios2.prx and libc.prx that Until Dawn
(CUSA02636) bundles have their PLT at 0xc8, at the start of the text
segment, before the code. In both, the last unwind function is
followed by the module's DT_FINI routine, which has no unwind entry,
and then by read-only data.

When no PLT follows the last unwind function, the search now also looks
before it. A PLT found there must not overlap an unwind function, and
the code extent then ends at the last unwind function, so what follows
it stays out of the scans and the code analysis, including code
without an unwind entry such as the DT_FINI routine of both modules
(recorded in the debt file). A missing PLT now fails with "PLT not
found before or after the unwind functions".
