[Tarantool-patches] [PATCH luajit v3 24/29] test: disable PUC-Rio test for syntax level error

[Sergey Kaplun via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

When LuaJIT is compiled with LUAJIT_ENABLE_GC64, LJ_MAX_SLOTS limit is
reached and error LJ_ERR_XSLOTS ("function or expression too complex")
is raised earlier, than LJ_MAX_XLEVEL limit is reached and error
LJ_ERR_XLEVELS ("chunk has too many syntax levels") is raised.
This happens, because, when GC64 support is enabled, every
function's call needs twice more slots on the coroutine stack
(since LJ_FR2 is also set).

This patch disabled the test expecting the LJ_ERR_XLEVEL error, but
failing with the LJ_ERR_XSLOTS error.
