[mlir] Convert 8-bit float types to i8
Whereas LLVM currently doesn't have any types for 8-bit floats, and
whereas existing 8-bit float APIs (for instance, the AMDGCN
intrinsics) take such floats as (packed) bytes, translate the MLIR
8-bit float types to i8 during LLVM lowering.
In order to not special-case arith.constant for bitcasting constants
to their integer form, amend the MLIR to LLVM translator to turn 8-bit
float constants into i8 constants with the same value (by use of
APFloat's bitcast method).
This change can be reverted once LLVM has 8-bit float types.
