Subject: [PATCH v2] disas/sparc: Fix integer overflow and convert to g_malloc
To: mark.cave-ayland@ilande.co.uk
Cc: qemu-devel@nongnu.org,
    qemu-trivial@nongnu.org

Replace standard C allocators with GLib functions to safely handle
out-of-memory aborts. Also change '1 << i' to '1ul << i' to prevent
undefined behavior when shifting into the sign bit. Resolves SVACE
warning and GitLab issue #1798.
