[mips] divide macro instruction cleanup. Clean up the implementation of divide macro expansion by getting rid of a FIXME regarding magic numbers and branch instructions. Match GAS' behaviour for expansion of ddiv / div in the two and three operand cases. Add the two operand alias for MIPSR6. Finally, optimize macro expansion cases where the divisior is the $zero register. Reviewers: slthakur Differential Revision: https://reviews.llvm.org/D29887 llvm-svn: 294960

[mips] divide macro instruction cleanup. Clean up the implementation of divide macro expansion by getting rid of a FIXME regarding magic numbers and branch instructions. Match GAS' behaviour for expansion of ddiv / div in the two and three operand cases. Add the two operand alias for MIPSR6. Finally, optimize macro expansion cases where the divisior is the $zero register. Reviewers: slthakur Differential Revision: https://reviews.llvm.org/D29887 llvm-svn: 294960
