[mips][microMIPS] Adding code size reduction pass for MicroMIPS Author: milena.vujosevic.janicic Reviewers: sdardis The code implements size reduction pass for MicroMIPS. Load and store instructions are examined and transformed, if possible. lw32 instruction is transformed into 16-bit instruction lwsp sw32 instruction is transformed into 16-bit instruction swsp Arithmetic instrcutions are examined and transformed, if possible. addu32 instruction is transformed into 16-bit instruction addu16 subu32 instruction is transformed into 16-bit instruction subu16 Differential Revision: https://reviews.llvm.org/D15144 llvm-svn: 301540
