35c7f5254b target/riscv/vector_helper: Fix build on 32-bit big endian hosts 
The code currently fails to compile on 32-bit big endian hosts:

 target/riscv/vector_helper.c: In function 'vext_clear':
 target/riscv/vector_helper.c:154:16: error: cast to pointer from integer
 of different size [-Werror=int-to-pointer-cast]
         memset((void *)((uintptr_t)tail & ~(7ULL)), 0, part1);
                ^
 target/riscv/vector_helper.c:155:16: error: cast to pointer from integer
 of different size [-Werror=int-to-pointer-cast]
         memset((void *)(((uintptr_t)tail + 8) & ~(7ULL)), 0, part2);
                ^
 cc1: all warnings being treated as errors

We should not use "long long" (i.e. 64-bit) values here to avoid the
problem. Switch to our QEMU_ALIGN_PTR_DOWN/UP macros instead.

Fixes: 751538d5da ("add vector stride load and store instructions")
