compiler: avoid crashing on invalid non-integer array length

Tweak the array type checking code to avoid crashing on array types
whose length expressions are explicit non-integer types (for example,
"float64(10)"). If such constructs are seen, issue an "invalid array
bound" error.

Fixes golang/go#13486.
