[PATCH] target/riscv: Fix checking of whether instruciton at 'pc_next' spans pages

This bug has a noticeable behavior of falling back to the main loop and respawning a redundant translation block including a single instruction when the end address of the compressive instruction is exactly on a page boundary, and slows down running system performance. Signed-off-by: Shaobo Song

[PATCH] This fixes a bug in POSIX-compliant environments. Since we had allocated a buffer named 'tcg-jit' with read-write access protections we need a int type to combine these access flags and return
