This is a resubmittal. For some reason it broke the bots yesterday but I cannot reproduce the problem and have scrubed my sources and even tested with llvm-lit -v --vg. Removal of redundant code and formatting fixes. Contributers: Jack Carter/Vladimir Medic git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172842 91177308-0d34-0410-b5e6-96231b3b80d8

# RUN:| FileCheck --check-prefix=MIPS64 %s
Expose move to/from coprocessor instructions in MIPS64 mode. Note: [D]M{T,F}CP2 is just a recommended encoding. Vendors often provide a custom CP2 that interprets instructions differently and may wish to add their own instructions that use this opcode. We should ensure that this is easy to do. I will probably add a 'has custom CP{0-3}' subtarget flag to make this easy: We want to avoid the GCC situation where every MIPS vendor makes a custom fork that breaks every other MIPS CPU and so can't be merged upstream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165711 91177308-0d34-0410-b5e6-96231b3b80d8
