Inline SMI checks in ICs are performed with a TBZ/TBNZ instruction, which has a 32 kB range. To allow patching the SMI check, the location of the TBZ/TBNZ instruction is stored after the call to the IC using a MOVZ instruction, in particular using 11 bits of the immediate (so the number of instructions between the inline data and the SMI check must be encodable in 11 bits). To make sure we do not exceed these ranges, we need to block pool emission between the check, the patch info, and the label the check branches to.
