haskell.compiler.native-bignum: don't evaluate compiler exprs 

This makes isNativeBignumGhc purely textual again after #460845.
Could improve performance in the right conditions, but most importantly
solves eval issues with aliases allowed (due to the throw-ing ghc
attributes) without resorting to tryEval.
