Matthew Dempsky a1b5cb1d04 cmd/compile: simplify isGoConst
The only ways to construct an OLITERAL node are (1) a basic literal
from the source package, (2) constant folding within evconst (which
only folds Go language constants), (3) the universal "nil" constant,
and (4) implicit conversions of nil to some concrete type.

Passes toolstash-check.
