This patch adds APFloat type support for the E2M1
FP4 datatype. The definitions for this format are
detailed in section 5.3.3 of the OCP specification,
which can be accessed here:

There is one test failure in Codegen/LoongArch/opt-pipeline.ll and it does not
seem related to my changes here.
So, merging this change.
