  [SelectionDAG] Remove unused float promotion in DAGTypeLegalizer (NFC) (#223219)

This patch removes PromotedFloats along with GetPromotedFloat and
SetPromotedFloat.  The Mapped bitmask in PerformExpensiveChecks is
adjusted accordingly, shifting the bit for SoftPromotedHalfs.

The last uses of DAGTypeLegalizer::GetPromotedFloat and
DAGTypeLegalizer::SetPromotedFloat were removed on January 26, 2026 in
commit a7d48bd305ef3aa4bd543da6f4cd8682a3d35c32 when TypePromoteFloat
and its associated DAG machinery were removed.

With these accessors gone, DAGTypeLegalizer::PromotedFloats is no longer
populated.
