[Mesa-dev] [PATCH 1/3] Revert "nir/opcodes: Use fpclassify() instead of isnormal() for ldexp"

[Jason Ekstrand]

This reverts commit d7d340fb2f68c46bd5a0008ecf53c6693e29c916.

We have an isnormal() implementation available, the only problem was that
we had the wrong return type (fixed in a later patch).
