This patch implements the expansion of the strlen builtin
using Zbb instructions (if available) for aligned strings
using the following sequence:
li a3,-1
addia4,a0,8
.L2: ld a5,0(a0)

This patch implements the expansion of the strlen builtin
using Zbb instructions (if available) for aligned strings
using the following sequence:
li a3,-1
addia4,a0,8
.L2: ld a5,0(a0)
