While they are represent 32/16 bit immediate values they are already included in encoding of the instructions that use them and are not true literals. FMAMK and FMAAK instructions that use them are marked with fixed size so getInstSizeInBytes will not increase the size for these operands. We also add tests whose logic relies on KIMM16 and KIMM32 being considered not inlinable. Differential Revision: https://reviews.llvm.org/D157624
