  Log Message:
  -----------
  [IR] Remove FP cast constant expressions (#71408)

Remove support for the fptrunc, fpext, fptoui, fptosi, uitofp and sitofp
constant expressions. All places creating them have been removed
beforehand, so this just removes the APIs and uses of these constant
expressions in tests.

With this, the only remaining FP operation that still has constant
expression support is fcmp.
