Cherry Zhang d21bdf125c cmd/compile: check SSAability in handling of INDEX of 1-element array
SSA can handle 1-element array, but only when the element type
is SSAable. When building SSA for INDEX of 1-element array, we
did not check the element type is SSAable. And when it's not,
it resulted in an unhandled SSA op.

Fixes #26120.
