all: add SliceToArrayPointer instruction

CL 332049 added support for slice to array pointer, which introduced in
go1.17, by using Convert instruction. However, the conversion can fail
dynamically, while all current conversion instructions can not. That
leads to inconsistent with other parts of SSA IR.

@timothy-king suggested to add new instruction for this conversion, this
CL implements that.

Fixes golang/go#46987
