Hardcoded 32 bytes is used for vbsrl emulation check, there is
problem when options lsx=on,lasx=off is used for vbsrl.v instruction
in TCG mode. It injects LASX exception rather LSX exception.
Here actual operand size is used.

On gen_ll, if a->imm is zero, make_address_x return src1,
but the load to destination may clobber src1. We use a new
destination to fix this problem.
