Thomas Tauber-Marshall e94c60833a IMPALA-6069: Fix CodegenAnyVal's handling of 'nan'
Previously, CodegenAnyVal used an LLVM function for floating point
comparison that considered 'nan' = 'nan' to be true. This is
inconsistent with the way we handle 'nan' in the non-codegen path,
where we consider 'nan' = 'nan' to be false, leading to inconsisent
results.

This patch fixes CodegenAnyVal to use an LLVM function for floating
point comparison that considers 'nan' = 'nan' to be false.

Testing:
- Added e2e tests for the two scenarios affected by this: CASE and
  joins.
